That's silly reasoning.
When Paul emphatically said flesh and blood cannot inherit the Kingdom of God, there is no other valid replacement clause given that would support your theory. Either you accept what Paul said as written, or you don't. It's apparent you don't.
Not only did Paul explain the why and how flesh and blood does not inherit the Kingdom of God in that 1 Cor.15 chapter, he even defined the TYPE OF BODY the resurrection is...
1 Cor 15:42-46
42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
Paul defined the resurrection body as that "spiritual body", even using that idea of "a quickening spirit".
1 Cor 15:48-50
48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
49 And as we have borne the image of the earthy,we shall also bear the image of the heavenly.
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
And that is why Jesus said you must be born again of the incorruptible seed, which is the One Living Spirit, Christ.
Jesus' New Man body was and is flesh and blood of the New Man DNA and the Spirit of that flesh creation is One Living Spirit/Christ.
If we are in the corruptible Adam flesh, and not born anew, from above, we will not inherit the kingdom of God, and our resurrected from the dust of this creation human being Adam flesh body will not be elementally dissolved and instantly transformed to the same flesh body that Jesus Christ is come in, and then we will be cast soul and body into the Lake of Fire, as cast aways, and there we will be never dying worms in that Adam flesh minus the Adam spirit bodies.
If we are not born anew, from above, of the incorruptible Seed, then we will be resurrected in our Adam corruption bodies, at the second resurrection of the dead, and then would be "never dying worms" in that body that is our own body, made for our own soul to wear.
Jesus paid the price for our first father's sin, and if we do not repent of our own sins done in the flesh body of the Adam nature, then we will be raised for the second death of eternal separation from the Father of Glory, and never, ever, ever, be transformed to the glorious image of the New creation Man, named Israel, not Adam, and have the Glory dwelling in us which is what Adam was made for, in the beginning.
Adam was made in the exact image, bodily, of God the Son, who is the image of the invisible God.
Genesis 1:26, 28, and Romans 5:14.
Jesus is YHWH the Word, who put on the garment made new in the womb of the virgin to reverse adopt Himself into the Adam creation so as to be the Kinsman/Redeemer [brother] to our bodies [Isaiah 59 -read it].
Jesus body is fully human and is fully human forever and forever. He is the Everlasting Father in that flesh body and the "God of the whole earth, in that body, which is what Adam had been made for, and lost in the fall when corruption entered at his defilement.
He is coming back in that same body, as Revelation 19 clearly shows, and Job, in chapter 19, totally knew the Gospel which Enoch wrote of, and was very familiar about the fact of God the Redeemer/Kinsman who would come, and who was God and who would resurrect his own body fully, even after it was dead, and that the Redeemer would stand on the earth in the last "Day" -the Millennial kingdom on earth, and that he, Job, would see Him with his own eyes of human being flesh, resurrected.
Jesus died for our bodily redemption and regeneration of the same, elementally, to the image that Adam was first made in, but with the New Creation, One Living Spirit from above, not the one, defiled, dead to the Glory, Adam spirit that we are all come into our being in, as the seed from the loins of him who was the first, firstborn human being son of God, who died in spirit [first death] and wears a corruptible flesh body that sin has the reign over and death reigns in.
The DNA of that New Creation human being flesh body is incorruptible and will be transformed to Glory as sons of God, which is what Adam was made to be in the beginning, to plant the heavens as a "temple not made with hands" for the Glory to indwell.
As to your quote of not marrying in heaven, but being equal to the angels, that is from Enoch the prophet, the seventh from Adam, who said the same, and Jesus rebuked the sadducees for not knowing that Scripture. Marrying is for the time before the transformation to Glory, while we are in the kingdom of God on earth.
After our "millennial day" was to finish, in Adam, then we were to transform to Glory without dying in the bodies, and to "plant the heavens", and that process was to go on forever, and in the New Man Living Spirit and flesh bodies, it will go on forever, to at least a million, million years;but not in Adam spirit or flesh, but in "Israel" New Creation flesh.
The ancient sages of Israel wrote of the purpose we were made for, and His purpose will go on forever.
After the flesh human being bodies of New Creation born on earth in the restored kingdom prepared for them from the beginning, live their "Day", then they will be transformed to Glory, without death, so as to be living stones of the temple not made with hands, which is what Adam was made male and female for, in the beginning, and made one one flesh, one bone, one blood, and one spirit, for. -Malachi 3:15
