It'd be pretty hard. You'd have to patch out the entire blitter code and
replace it with your own work-alike, or else constrain your app to not
allow any system dialogs (alarms, low battery, incoming IR...) to appear
when you're in 4-bit mode. It is only software, so it isn't as if it can't
be done; it is a "simple matter of programming" as they say.

Same answer, but this time you'd be needing us to do the work, and I
wouldn't hold your breath. You can get the 3.3 or 3.5 updates which get
you to the same goal with zero engineering effort :-)
