You only need to supply one track at a time--and you can hold off the 
controller for any swapping you might need to do for a few msec. by 
delaying the index pulse. An ST-412 track (surface) holds less than a 
track on a 1.44MB floppy--it just spins 12x as fast.

I think it's probably quite doable if there's a market for it.
