My concept is no more outrageous than this link to this gentleman's prototypes, who turned a Remy 11 upside down and welded an attachment for a MG42 type trigger group and grip to it.

That being said, here's my concept. First my rough cobbled together pic I did in "paint". Then I'll explain it (although the pic is almost self explanatory).
The loading tube is removed (obviously). A bushing is affixed to the front of the receiver that the barrel fits thru and clears. That bushing is for the rear of the recoil spring to rest against. There is another bushing on the barrel that is attached via multiple set screws (that dig into, but not thru the barrel) and it is removable to replace the recoil spring. The bushing on the barrel presses against the recoil spring and serves the function of returning the barrel to battery following recoil. You could actually use a friction ring at the rear of the spring that would friction against the sides of the barrel (instead of the loading tube) to slow down barrel recoil.
Some sort of over the barrel handguard could be worked up to cover over the spring to avoid any improperly placed pinched hands when the spring is compressed under recoil. The shell lifter would be removed as would a few other internal parts that have to do with blocking the shell rims having to do with the regular system of the tube loading. With the loading tube removed, there would be room to do some milling to increase the size of the rectangular hole on the bottom so a 12 gauge magazine or drum could be affixed and the catch for it welded on. With the loading tube omitted, you could use a metal piece going forward from the bottom of the receiver to attach either a vertical (think Thompson sub MG) or a horizontal grip. I can not get the same thing with an Origin 12, a Saiga 12 or a Vepr 12 since they are gas operated and not recoil operated.
It's just an academic concept and I doubt I'd take it on with all my other projects, but what helpful to the redesign concept suggestions does anyone have (besides telling me to not do it and leave it alone)?
