Several pins are defined differently.  The ease of hacking the alternate
pinout into an existing design depends mostly on how easy it is to chew
up the connections between Agnus and the DRAM array and insert additional
logic and/or make connections to an external DRAM array.

You'd have to talk to the Rejuvinator people about their plans/position
in this respect.
