If the auction happens, I think it's pretty obvious that the material will fall into the wrong hands. But understanding that, out of all the people who are likely to buy it, who would you want to have control over it?
I'd say Jay-Z. He has easy access to damn near every hot producer in hip-hop and even some non-hip-hop heads... Linkin Park, Lenny Kravitz, etc., plus I doubt he'd turn Pac songs into a Roc-a-fella posse cut. It'd be better than Puffy, 50, Eminem, or any of those dickheads buying it and turning it into garbage.
