That's one of those things that pops up throughout history: Who could one spar with to get ready for Ray Robinson? No one could duplicate his skill and physical abilities. For Roy Jones Jr.? No one on earth could imitate his style, much less his speed. Did people spar with battleships to get ready to stand up to George Foreman? I agree that no one can adequately duplicate Money's physical abilities, but I don't think his style is something that is impossible to prepare for. It just happens a lot faster in the ring, and he's going to be much harder to hit than any sparring partner.
Just get sparring partners that are very skilled. If you spar them, then you'll build your overall skills and that can help you.
He'll probably get a lot of fast guys that can move a bit. Hopefully he spars in 5 min+ rounds with possibly rotating sparring partners. He's a professional, I am sure he will use all of his resources and be the absolute most prepared he can be.
I agree that it would be almost impossible. But you could find different sparring partners with certain attributes similar to Floyd and then in combination, it could help you. For instance, you could get Zab Judah to help you prepare for hand speed.
