That doesn't quite seem to square with 1 Cor. 15 where we read:
23 But each one in his own order: Christ the firstfruits, afterward those who are Christ's at His coming. 24 Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26 The last enemy that will be destroyed is death.Note that it does not say " afterward those who are Christ's at His coming. Then comes the millennium". It say "then comes the end". It also does not say "then comes seven years of tribulation followed the real second coming followed by the millennium then comes the end". From this text we see clearly that "the end" involves the final conquest of all Christs enemies including death (and by implication sin also). There is no room in this passage for a "thousand years" of spiritual resurrected folk living among natural, sinful non-resurrected folk.
"Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption." (1 Cor. 15:50)

Vs 25 says that Christ must reign till all of his enemies are put under his feet.
That reign happens during the Millennial reign (see Ps.2)
Then, the last enemy destroyed is death, which happens at the Great White Throne Judgement (Rev.20)
Now, as for 'flesh and blood inheriting the Kingdom of God' you know that the Kingdom of God and Heaven are two different Kingdoms!
The Kingdom of God is a spiritual Kingdom which flesh and blood cannot inherit (Rom.14:17).
The Kingdom of Heaven is a literal, physical kingdom, which is the Kingdom the Apostles were looking for.
In the Millennial reign the Kingdoms come together and both coexist as one, but remain distinct from each other.
In the eternal state, that will also be true, but the difference is that there is no more death, no more rebellion, no more sin.
