It looks like the Rowan TX200 hamster could be made to work. I am looking at the TX and 97 now, the 97 action screw is .27" deeper in the stock than the TX. Either a spacer there or countersinking the front post should make it fit. (just going off the way it looks to fit in the pictures, I don't have the hamster in hand) Or you could just install threaded inserts like I did with my Discovery and carve out a scrap piece of walnut to fit. I wouldn't do the rail unless it was inletted, and there isn't much material towards the cocking lever slot.
