For what it's worth, 68HC11 in FPGA seems to be a "hotter" technology than 6809 (or at least you can purchase commercial license/support). Not sure if that migration path would be appropriate for your project or not.

Where to start? After you pick which soft core you want to start with, I would suggest getting a sanity check in ModelSim with it executing your existing software and adding enough to the testbench to exercise the critical functions like the licensing you mentioned above. When you're happy enough with the results it ought to be simple enough to wire from the headers on a board like the BeMicro CV to the 6809 socket on your existing board and see how much trouble you're in.

Good luck.
