There's definitely a way to do it. While I'm not sure how, my friend who has no idea what he's doing when it comes to editing the PM files started messing with either common3 or common5 in Brawl Box. Obviously, since he was uneducated it didn't work out the way he expected. On that note, however, when we launched Project M it played vBrawl's intro and brought us to vBrawl's menu. Everything was vBrawl in fact except for Stage Select and CSS. So, I suppose wait for someone who knows more about editing.
Even if there isn't a way to do it without screwing up some part of the game, there must be a modded HUD that looks somewhat like vBrawl's.
