Compilation environment is pretty much irrelevant because they'd have to redo the environment-dependent parts will have to be rewritten anyway for HD support. Porting from one compilation environment (NOT platform) to another isn't a too complicated action anyway. Not sure about models, but there should be enough tools to allow converting them from an old format to a newer one.
The 3D-2D scenes are quite tricky though, but hopefully in the theoretical case they remake the game in HD they shouldn't be very hard to reproduce.
