It doesn't seem to difficult to me to do, from the X API/protocol
side. Sure some very weird programs expecting static Screen linkage
will get confused, but users needing such will just have to 
disable the new features: nothing lost, nothing gained for them.
If your X server code can't with reasonable effort be modified 
to handle that.. well, you've done some really crappy code. 

Anyway, once root windows are fully dynamic -- when X has a 
dynamic multi-display "model" layer -- you could so far as
restoring xinerama/xvidmode/stuff as the "view" layer, mapping
any part of any window to any physical display, that can display
the visual chosen for the window. (Different windows could even
be mapped to different virtual consoles, assuming there's any 
point to that.) I think this could work nicely together with 
Composite (and its troubles): want to bypass composite indirectness
for a full-screen (game) window? Just map it directly to a screen.
