Hmm, I was thinking of:

sys.register_importer(myimporter)
sys.path.append(p)

myimporter would then either be asked for a suitable suffix
or prefix to use in matching or the importer would simply
call myimporter.match() during the sys.path scan.

Sounds like the classical "you need one more line than me"
argument ;-)
