I admit I didn't read the whole thread, but if you want to attach something 
to the three ROM sockets in a C64, you know that all data and address lines 
are the same on all sockets, and the difference is only in the three chip 
select lines? So it's enough to attach to one socket and pick up the 
remaining chip select lines from the other sockets with a wire, or maybe 
you can have a PCB with different holes for different ROM spacings for only 
these two signals.

This should work well as long as you don't choose the character ROM socket 
because this might lack one address line.
