My issues with BrawlBox are that you're limited to FK animation and it's graph editor isn't too good (poor control over key tangents) , which makes animating tedious. If you're not already decent at 3D animation, I wouldn't recommend BB. I've only seen a few decent animations made strictly in BB.
Of course, you can import animations from Maya, if you have it.
Though, yeah, I agree that making a Brawl mod still be would be easier. Movesets will have to be changed, but now all you have to do is make content.
