They are able to switch around brawl models.i'm not a part of this project, but i think that replacing lucario is for the time being because all the other options are not possible (yet)
once they are able to import any type of model into brawl, they would most likely put it over a worthless character, and then when the clone engine comes out they will not need to replace any1
this might not be true, but its what i think they will do
Replacing another brawler with lucario, if I'm right, would only be affected by the count of bones, and, depending on the character, swordglow. They've been replacing Pokemon and assist trophies over alloys and characters like Olimar.
I'm also sure I've seen some other models replaced in this thread as well.
