What you could probably do is remove the head preamp IC and stepper motor

a Shugart-type FDD interface, but it might be worth a shot (on a drive with a
truly buggered mechanism).
Or you could build a new 1541 mainboard from scratch and mod the circuit to
provide a Shugart FDD interface, which might be a bit easier. ISTR there's
some stuff on the inner workings of the 1541 on Ruud Baltissen's site,
including some info on the inner workings of the 1541 LSI controller.

I'm not sure you'd be able to swap it out
- isn't the head preamp on the
1541
motherboard, not a separate drive interface board?
Indeed it is. I hoped that perhaps generations of C128 hackers had found a
way around this by now. Silly me.
