You're asking for a pretty massive undertaking there, G. If you're asking for "help", you might consider posting what you have so far so we can build on it.
My personal favorite of the Capcom/Inti sound guys is Ippo Yamada, having done the majority of Zero/ZX music, and in particular the sheer awesomeness that is Straight Ahead (Z4) and Cannon Ball -Hard Revenge- (ZX).
Here are the composers that I found listed in the Zero/ZX remastered albums:
Z1
Ippo Yamada
Setsuo Yamamoto (Capcom, not Inti, credited for Zero's X1 theme)
Z2
Chicken Mob
Ippo Yamada
Luna Umegaki
Masaki Suzuki
Tsutomu Kurihara
Z3
Ippo Yamada (literally credited for everything except Suzuki's three tracks)
Luna Umegaki (w/ Yamada on Darkelf -Arrange-, and Labo -System-a-Ciel-)
Makoto Tomazawa (w/ Yamada on Scrapped Beat)
Masaki Suzuki (Volcano, Water City, and Old Life Space)
Tsutomu Kurihara(w/Yamada on Sand Triangle II)
Z4
Chicken Mob
Ippo Yamada
Luna Umegaki
Masaki Suzuki
Shin'ichi Itakura
ZX
Ippo Yamada
Masaki Suzuki
Ryo Kawakami (Rockin' On, baby!)
It occurs to me that I never scanned ZXA Tunes, which is in my car at the moment.
