Only if he could do a better job negotiating licenses and getting key characters from PlayStation history like Cloud, Sephiroth, Crash Bandicoot, etc. Sony doesn't really have an interesting enough roster of characters on its own to carry a mascot fighting game the way Nintendo does.
Also, as someone noted above, I think Sony should have gone with a 3-D fighting style. A Sony mascot fighter would be better off in the hands of Team Soul, Katsuhiro Hirada (producer of Tekken), or Sega AM2, which could produce such games.
