I think that's possible, but it would require a completely new
programmer implementation, source code file, avrdude.conf grammar,
etc.  You can perhaps clone one of the existing implementations for
that.

Another option might be to use the -x option for that.  It's intended
to pass options down to the individual programmer implementation, so
you could e.g. add an option like "-x crc" to an existing programmer
(like stk500v2).

Personally, I'd prefer the first variant.
