Those are interesting thoughts, but, at this time I don't see the Scriptures saying we spend a thousand years in heaven. That means, Adam will have been in heaven 8,000 years by then.
God created the Earth for man to inhabit, not heaven.
Isa_45:18 For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.
A thousand years in heaven makes no sense. When Christ returns to the Mt. of Olives, we will be caught up with him, and given our glorified bodies at that moment, in my reading of the Scriptures. Heaven is a spiritual domain and man was made to live in a physical domain. Yes, two physical men are in heaven right now, Elijah and Enoch, but they are special cases.
But, as I said, I had never heard that view before, and it is something to think about further.
Heaven is a spiritual domain and man was made to live in a physical domain.
and when He returns, we will be changed and given spiritual bodies.
1 John 3:2
Beloved, now we are children of God, and it has not appeared as yet what we shall be. We know that,
when He appears,
we shall be like Him, because we shall see Him just as He is.
At the transfiguration, Jesus shone with a bright light.
Matthew 17:2
And He was transfigured before them; and His face shone like the sun, and His garments became as white as light.
1 Corinthians 15:44
It is sown a physical body, it is raised a spiritual body. If there is a physical body, there is also a spiritual body.
The millennium is the thousand-year reign of Christ with His saints in heaven between the first and second resurrections. During this time the wicked dead will be judged; the earth will be utterly desolate, without living human inhabitants, but occupied by Satan and his angels (nobody to tempt, "in prison" - bound) .
At its close, Christ with His saints and the Holy City will descend from heaven to earth. The unrighteous dead will then be resurrected, and with Satan and his angels will surround the city; but fire from God will consume them and cleanse the earth. The universe will thus be freed of sin and sinners forever. Revelation 20
1 Corinthians 6:2, 3 Jeremiah 4:23-26
Revelation 21:1-5 Malachi 4:1 Ezekiel 28:18, 19
A thousand years in heaven makes no sense.
1st Corinthians 6
Do you not know that we will judge angels? How much more the things of this life!
Satan and his minions Bound to the desolate earth for the 1,000 years - nobody to tempt
Revelation 20
1Then I saw an angel coming down from heaven with the key to the Abyss, holding in his hand a great chain.
2He seized the dragon, that ancient serpent who is the devil and Satan, and bound him
for a thousand years.
3And he threw him into the *Abyss, shut it, and sealed it over him,
so that he could not deceive the nations until the thousand years were complete. After that, he must be released for a brief period of time.
*Abyss ... same condition as described in Genesis, before creation.
Genesis 1:2
Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
the deep - Hebrew meaning (Strongs)
tehom: deep, sea, abyss

Then the 2nd resurrection happens - after the 1,000 years.
That means, Adam will have been in heaven 8,000 years by then.
So, evidentially you believe when one dies they go to heaven or hell? Rather than resting in the grave until the Lord returns?
We are sort of getting off topic .... common to do ;o)
So, back to the OP, no there will be no marriage in heaven ... Jesus is clear on that point.
Matthew 22:30
For when the dead rise, they will neither marry nor be given in marriage. In this respect they will be like the angels in heaven.
Luke 17:27 - Jesus speaking
27 Just as it was in the days of Noah, so also will it be in the days of the Son of Man: 27
People were eating and drinking, marrying and being given in marriage, up to the day Noah entered the ark. Then the flood came
and destroyed them all.
