For over a year, I have been suggesting that an extended-frame Super Redhawk could be chambered for a cartridge based on the 500 S&W, but a fraction longer, for no other reason than to make the Smith no longer the most powerful production handgun in the world. I would call the cartridge the "500 Bill" for the obvious reason.
So far, no comment from Sturm, Ruger.
This goes along with my suggestion reintroduce the Security Six chambered for the 22 LR with 8 to 10 (however many can fit) chambers in the cylinder. (And, for Pete's sake, put more chambers in the SP101 22 LR and bring it back, too.)
Also, my suggestion to put a Dan Wesson style interchangeable barrel on the Super Redhawk, at least, if not the GP100, too, and the reintroduced Security Six from my earlier suggestion.
Lost Sheep.
