   Another possibility is to use the elimination macros (ie, define a
   new register which is the stack pointer without the bias, and then
   eliminate to the real register via subtraction.

Interesting.

My one concern with this approach is that this modifies the range (via
immediate offsets) which can be reached relative to the real stack,
since it will be working with a virtual stack pointer.

Or do the elimination macros handle all of this transparently (or can
be made to do so)?
