Well, the beasts are kings. And it is also clear the beast are kingdoms. To me, this makes it perfectly reasonable and logical that they are all more or less interchangeable. If beast = king, and beast = kingdom, then it is implied that king = kingdom. This is a matter of basic logic. Certainly, the possibility of this assertion cannot be simply cast away. In practice, this means is that peices of the puzzle are less constrained that one might have initial thought.
No, it is not logical what you are saying, but a mistake in logic.
I will explain with an example of why not.
A NFL team can be the Denver Broncos or the Dallas Cowboys. By your logic that would also mean that the Denver Broncos can be the Dallas Cowboys. Which is false.
By sticking to what it says in Daniel 7, beast can be a kingdom or a king.
Not that kings and kingdoms equate to each other.
In the case of the 7 kings, those are of one kingdom the fourth empire.
in Revelation 13, the first beast represents a kingdom (the fourth empire) and a king (the eighth king).
in Daniel 7, the fourth beast has one head - that one head is the eighth king. And because the little horn is on that one head - he is associated
with the eighth king. As are the ten other horns on the head in Daniel 7. Those ten horns are the ten kings in Revelation 17 that give their kingdom (the fourth empire) to the eighth king when he rules.
It just so happens that the ten kings are also of the fourth kingdom when the little horn come to power.
What that all boils down to in actual recognizable terms is the fourth empire end times is the EU. The ten kings (leaders) will be the final form of the EU government, with one leader over them the little horn. He is the 7th king, yet to come of Revelation 17.
He eventually becomes the Antichrist, king of Israel, for a stint. And then is rejected by the Jews as their king, ending his stint as the Antichrist. Is killed and brought back to life, claiming to be God, as the beast. Now he is the eighth king, because his original EU powerbase pledge their kingdom to him (as they buy into his claim of being God), which he will rule unopposed.
So the person is the 7th king of the Roman Empire and continues for a short space of 42 months as the 8th king of the Roman Empire.
10 And there are seven kings: five are fallen, and one is, and the other is not yet come
[#7]; and when he cometh
, he must continue a short space.[the 42 months. as becomes the 8th king] 11 And the beast that was, and is not, even he is the eighth, and is of the seven, and goeth into perdition.
12 And the ten horns which thou sawest are
ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.
Now if you read Daniel 7.
19 Then I would know the truth
of the fourth beast, which was diverse from all the others, exceeding dreadful, whose teeth were of iron, and his nails of brass; which devoured, brake in pieces, and stamped the residue with his feet;
20 And
of the ten horns that were in his head [the head is the beast and the ten kings give their kingdom to him in Revelation 17], and of the other which came up
[the little horn 7th king], and before whom three fell; even of that horn that had eyes, and a mouth that spake very great things, whose look was more stout than his fellows.
21 I beheld, and the same horn
[after he becomes the beast the 8th king] made war with the saints, and prevailed against them;
The ten kings are associated with the 7th king - the little horn (Daniel 7).
The ten kings are associated with the 8th king - the beast (Revelation 17).
Because the little horn becomes the beast after being killed and come back to life.
