Question about Installing a Mod

I'm playing the original BG2 + TOB (non-EE) and currently I have Ascension, SCS2, G3 fixpacks, and widescreen mods installed on the game. I'm currently at the Oasis in TOB.

I've been reading more about mods and I'd like to do the Ritual and Eclipse battles that come with the Solefien mod.

Was curious if anyone knew if I could install it now at this point in the game w/o messing up the mods I currently have.

Sorry if this is the wrong BG forums as it seems like its dedicated to the EE edition and BG2 and TOB aren't even out for it yet.

Thanks in advance
