I think the fatal flaw there may be pinout.  I'm not certain that the
newer USB parts are pin compatible-  IIRC, the C7x5 PICs use the
RC6/RC7 pins as USB, while at least the 18F that I saw the pinout for
most recently reserves those for a USART and uses RC4/RC5 (again,
from memory) for USB.  It's still worth a look- but at that point, you
almost may as well be writing your own programmer.
