Game mod suggestions for 30XX

A list of stuff I might recommend to peeps working on a certain mod for 30XX which makes it actually feel like a MMX game again that I know well and a bit better or worse (but far better). So far I like how even if after MMX-Dive is done, that in this one I can still go as soul of Ico from MMX-Dive and she acts like X in almost every way which is a big plus for me lol. Anyway, current suggestions both possible and impossible for now are on my list to the modders in the future, though I expect others to be against my choices:

Possible:
Music change for a few parts-
Final Stage 1 (Elanor's Fortress);

St 9.A (Space) - Gateway from MMX8
(original)

St 9 Midboss (Dragon) - "Nightmare Mother D-1000 Redux" remix from MMX6 (better choice because: 1-Midboss, 2-more guitars suitable for the project, 3- shorter)

rejected suggestion:

St 9.B (Fortress) - Lenny Lederman's "Sigma Fortress 1 Remix" theme
https://www.youtube.com/watch?v=4PKx6kaWJ9M

St 9 Boss (Elanor/Vile) - Lenny Lederman's "Battle with Double Arrangement"

Warning!: (will have to edit this and send directly...)

Final Stage 2 (Beast of Disaster);

St F-A (Bio-organic monster's exterior) - MMX2 Opening Stage Remix (dunno why...)

a change in plans:

St F-B (Bio-Organic monster's interiors) - Lenny Lederman's "Gate's Lab Full Arrangement" theme (already voted to them, but in this order now)
