No chance to get a "larger" (i.e. with more gates) CPLD that would fit the same socket ?... Or perhaps by using a modern and larger (in both size and number of gates) CPLD that would piggy-back on the old CPLD socket via a small adpater printed circuit ?...

That's definitely not a problem then: I've seen (and did) hardware mods with more "flying" wires than this... However, another issue with this solution could be the lack of room to piggy-back a daughter board on the EPROM slots, especially with the 2 ISA slots occupied and a heat-sink+fan on the 68060... > .../... > He owns a multisync *flatscreen*.
