Hmm, on my school bus (a "regular" one) I might consider cutting off just the flange at the top, but I don't think I would want to cut it that close to the floor (some people here have done so, at least in a couple of gaps so they could move their door).
I've cut my own bus open so I understand how it's structured pretty well. With shorties like yours, I don't really understand how they're built (although I imagine it's similar) so I don't know if this is a good idea not. Seems like a lot of work, though, that you could avoid by just building your interior wall over it, even if it has to stick out a little bit.
