After the program starts running, nothing alters the IRP bit except an
explicit write to it (or the STATUS register).  Check out my IBANKIF and
related macros in STD.INS.ASPIC at http://www.embedinc.com/pic/.  If used
properly, these will let you indicate which indirect bank is to be selected
at any time, but will only cause instructions to be emitted when necessary.
