Yup. I have done the same kind of thing with GALs (which offer the
convenience of re-programming, though not the longevity of a PAL.)
Did this as a backup for the Signetics chips on a Mark 8.
You can see them in this Flickr stream - I had both "normal" and open
collector variants, and designed both chip-specific and generic boards
for chip replacement (I expect to run into the issue with DTL as well).
BTW, I sent my PCBs out to Gold Phoenix PCB - http://www.goldphoenixpcb.com/
