Sure, it's possible.

Does the benefit of this compensate for the overhead of the additional 
cpu cycles on every exception/interrupt entry/exit? At least the normal 
COMPAT_15 behaviour can be disabled by simply no defining the option.

You'd also have to add the same overhead to the FIQ entry/exit points 
"Just In Case".
