There is no problem with epoxy molding to the recoil slot. You would slide the lug all the way forward before gluing it on with super glue. Like on any gun, the epoxy molds to the voids in the action regardless. Technically, you don't even have to pop the lug off after bedding. It won't move, because it will be surrounded by the epoxy. I would not tape the front of the lug like on a remington. You don't want a gap there.
Using something solid like marine-tex or devcon would be the best bet.
