I'd be down for this. 

If possible, I'd like to play a diplomat or negotiator.  Not much of a fighter, but someone who wields influence and wealth, forming pacts and agreements to shape things in her favor while offering indirect aid to sides and individuals who might further her aims.  I'd imagine she'd be the leader of some sort of merchant's guild, and with alchemy dying out would be seeking to preserve and monopolize the remaining knowledge of the art.
