It is suprising how little the overhead required to do that is. You just have to add a little overhead to your make/undo routines, and then you can use the 16x16 stuff or bitboards, whichever is more advantageous for the given problem at hand. Ideally, I would like to have an engine with compiler switches that would allow me to toggle various things on and off. For instance, on 32-bit hardware I could compile it to use the 16x16 move generator, but on 64-bit hardware I might want to use the bitboard move generator. It would be very nice to be able to make a change like that by adding a #define to the code. Then you could compile it for PDA, 32-bit, or 64-bit and have it run fast on anything.
