I could see Bowe replacing Patterson, it's just that Patterson was a force among heavyweights for a longer period of time than Bowe was. Taking your bracket, however:

1.Ali vs Tunney = Ali
2.Holmes vs Walcott = Holmes
3.Lewis (I wouldn't have Lewis this high, however) vs Bowe = Lewis
4.Louis vs Charles = Louis
5.Holyfield vs Liston = that's frieking tough..
6.Johnson vs Dempsey = Johnson
7.Foreman vs Tyson = I think Tyson could win a decision, much like Morrison did: stay at mid-range, and use his surperior hands speed and elusiveness to outscore him. I absolutely disagree with the idea that this fight would end up like Foreman-Frazier.
8.Marciano vs Frazier = 87 rounds
