Option B is more desire-able, but a Herculean task. P&N and Devnull are already pretty huge and complete, and not necessarily compatible, no?

Option A is more do-able, but personally I recommend just taking over an available slot from a PBW in progress. I find starting with a real (and not "balanced") game history quite interesting and more desirable than balance (achieve balance through skill, cunning, and diplomacy), but that's just me.

Having the AI run the first turns is also an initially fair, even if the results won't be necessarily balanced.
