I'll add onto the pile of questions by asking if we can change digivolution lines up from canon?

In my particular case, I'm thinking I'd like to have the Terriermon line, but to replace MegaGargomon with Fuujinmon as the Mega-level form. I like his design much more than MegaGargomon's, and have always felt that he seemed like a relatively natural digivolution from Rapidmon, just playing on the speed aspect of Rapidmon more than the walking artillery traits like MegaGargomon does.
