First off, this is not for dispute, but info. Did anyone ever fit a rebounding lock to a percussion (ML'r) gun, can't recall ever seeing reference to one. The hammer would still need to be drawn to full cock for capping anyway, so would seem to not be an important factor for them. I do realize of course a "Cartridge Gun" is fired by percussion to its primer but the term "percussion doubles" to me just means a ML'r fired by percussion caps. The rebounding lock was, IMO, a great development for the breech loading hammer gun.
