How many current top LHWS can Prime Ali go through without stopping?

Assuming you take the best version of Ali and forces him to fight the top LHWS in the World without stopping. How many do you think he could possibly go through before losing or getting stopped? I choose Ali because he's still 6'3 and around 215 pounds. He also rarely displayed ATG Power(like Lennox or Foreman) So Ali would actually find it tougher to go through this list than say a 6'5 245 Pound Lewis who can just punch everybody to death in the first round. Hence never getting tired. I think it's common sense he wipes out Stevenson first. He'll have little trouble taking on Sergei and Bernard right after Stevenson. But after that it gets tricky. 1-Stevenson(Ali KO 4) 2-Kovalev(Ali KO 4-5) 3-Hopkins(Ali TKO4-5) This is when Ali began to get tired and starts getting a bit sloppy. Less snap on his punches. 4-Pascal(Ali KO 10) 5-JUERGEN BRAEHMER(Ali KO11) This is when Ali starts getting tagged and is definitely going life and death now. 6-BEIBUT SHUMENOV (Ali Tko11) I don't see him doing well beyond this point. So my guess is that Ali would defeat the top 6 LHW'S today in one night before finally falling.
