Nightly 55k on FTP, I 4bet shove KQo, good or bad?

[pokeriseasy]

I have been playing pretty crazy, CO has been at my table for about 30 minutes and in that time I'm probably raising 30-35% of my hands but I have only shown down solid hands He's also being somewhat aggro, I have seen him 3bet twice once he 3bet squeezed shoved from BB but he had AA. He's also been opening a fair amount. Given these facts is his range wide enough that he's folding the majority of his hands in this spot?
