So, whilst helping a friend with an entirely seperate project, I found an old Japanese webstite, with pages for many different games. And, on the page for SFA3, every character's generic and character specific win quote is listed.
You can find them through the sub-sections of this page:

Towards the bottom. This also includes the PSX/DC exclusive characters (Guile and remaining SSF2 New Challengers), but not the GBA/PSP ones (Eagle, Maki, Yun & Ingrid), unfortunately.
Hopefully you can get some neat little tidbits from the dialogue about your favourite characters.
