Ooh, missed this thread. I'm a big BF'er, but I hadn't seen this thread. This looks like one of those mods that isn't going anywhere, though.
Shin Matsunaga (active on quite a few gundam sites, runs the "den of the white wolf" site, etc...) was talking about an idea for a gundam BF mod at the Soldier 9 Realism (now XWWII) forums a while ago, one that would focus on infantry and vehicle combat, and only would feature MS in small numbers, and nothing more than a GM / Zaku. I don't think anything ever came of it, though.
