Kos-mos(Xenosaga)- A super hot robot chick that can turn her arms into blades/larger machine guns and shoot energy blades...need I say more
Haseo(.hack// G.U.) in the trilogy specailly the 3rd, you could switch to from dual blades, to broadsword, from sythe, to guns!!! that would make for some awesome combo moves!!
Kat(Gravity Rush) I don't know why, but I just think she'd fit in
Gabriel Belmont(Castlevania: LoS) since I'm currently do a plat run I would just like to see him in it :p
Cloud or Lighting(FFVII/FFXIII both sword users, that alone would make them perfect fits, and their fandom alone would push for some extra sales
and for you bristow, I would chose Prince from Prince of Persia 2008 :) (maybe ubisoft would realize they need to make a sequel)
