There's probably no real guide to it.  Remember that AVRDUDE merely
evolved into what it is, rather than having been designed ground up.
It started out as Brian Dean's little project to drive his
parallel-port attached programming dongle under FreeBSD.

Usually, one picks the closest programmer implementation that seems
appropriate, and then modifies it.

However, since you say it might be based on USBasp, you might consider
tweaking the USBasp implementation to accomodate for the clone device.

I don't think that's worth the while.  First, it will only help Linux
users (leaving all other Unix users, including OSX, out), and then, I
guess you have to duplicate a lot of the higher-level code from
AVRDUDE.
