I'm giving some thought to running two versions of the game for two separate groups, but I won't make any promises.

Wouldn't recommend it for the sake of your sanity. GMing even one group is kind of a pain, and keeping track of two at once means your workload is also doubled. It's not just keeping track of everyone, but also double the amount of writing you need to do, and that adds up quickly.
