Yes, it would.  Of course, you need to resolve the conflicts between
your bootloader and main application manually, in particular you need
to relocate the stack for the main app as by default, the stack starts
right on top.

I'd personally consider it not a very eloquent solution, and rather
implement two completely independent pieces of software.

Yes, you need to.
