Well, actually your general idea (as originally presented) sounded like a fun one to me, and had a lot of things I liked and none of the things I don't so I was rather intrigued from the moment I discoverd this thread and dusted it off a bit.
I was thinking of perhaps playing as either an amazon general (or maybe the queen as a futa) if there's others interested. I think you can count Kunoichi in
and perhaps Transgirlinstein might still be interested.
If you are still willing to run it, rahatng, I'd be willing to create a character for it.
