Thinking about using an XC95144XL because of its high pin-count. This will allow me to route the entire address bus plus all the PDS signalling, as well as all the special control and handshake lines from the 68030 as well. 

This gives me room for experimentation of the logic without the need of re-spinning the board. I think these CPLDs have enough drive current to manipulate the bus directly using internal buffers. Save costs, but scouring the datasheet to be sure.
