You could probably get those output frequencies with a custom version of
the PIC code. There shouldn't be any hardware changes needed, though
the circuit board layout wasn't optimized for high frequencies so no
guarantee on 5 MHz.
The PIC source code will be available, so anyone who wants to modify it
for other outputs can have at it.
