did you know you can keep using SW's rivermod alongside with MA? just keep stormworld_rivermod , gfx and stormworld_shared folders in mods, and keep using rivermod's terraintypes.xml .
Yes. I just wish the other parts worked as seamlessly together.
for that matter, did you know you can use WAC alongside with FCOM?
Yes. 
WAC and Warcry didn't interest me enough to install, though, and Oscuro conflicted with too many other mods I'd decided to run. So I ended up with Francesco's, Mart's, a ton of large and medium quest mods, a lot of little stuff that makes life interesting, about half a dozen companion mods, the complete Armamentarium, a house mod with my own tweaks, and a few compilation mods I built since I was running over the mod limit. Everything works well together, and I'm often surprised by unusual encounters and some ridiculously powerful adversaries.
Oh, and I use my own released mod, too! Skin-toned Mannequins:
http://oblivion.nexusmods.com/mods/31218
The only Oblivion mod that provides mannequins for every race and both sexes, complete with melee/ranged/magical posing, inventory management, casting left/right/both hands to self/touch/target, and easy pick up/dropping. I just couldn't stand the fact that we had nothing but uniform wood or marble mannequins for so long. Scripting was a real bitch, and having to literally move 140+ one by one to a created control zone for separate purchase was no better, but I think it was worth it.
