Knoxx adapter?

[rtsj]

 I have a browning bps and was wondering if an adapter plate of some kind could be made to get either a mossberg or a rem knoxx stock to fit. I would be making it out of aluminum, or just be modifying the end of the knoxx to fit into the Bps. Is it possible or just a waste of time? Really want a knoxx stock on this gun. Thanks Roy  Any other ideas would be appreciated.
