OK, how about one step at a time.  It's already a huge step to move
things around (between Kconfig, and tangled source, and headers...).
The advantage of move towards a known target (sub-arch) is there's
infrastructure in place to support it already.  I don't think it's a
dead-end to go there and then look towards the issues you brought up.

Things move all the time, it's just a simple matter of patching ;-)
Or did I misunderstand you?
