VC1541 with fast serial?

Hi there,

has anyone actually every tried to convert the VC1541 to use the fast serial 
bus of the C128?

As I see it, on the UC3 VIA here http://www.zimmers.net/anonftp/pub/cbm/
schematics/drives/new/1541/short-251748-rev.E-left.gif there still are 

- Port A0-7
- CB1 
- CB2 

unconnected. These could be used to 

- CB1/2 shift out under T2 control and
- PA0-7: connected to a 74LS164 serial-to-parallel shift-in register

The only other thing needed would probably be a 74LS14 Schmitt trigger input 
driver, a 7406 output driver, and potentially replacing the PB6 drive ID input 
with an SRQIN input, and of course a fly-wire to the IEC's SRQIN pin 1.

What do you think?
