OK, I tried to treat this as a serious "what if/how would this be done" type of discussion, but you're off in the weeds now, throwing around unquantified and unquantifiable terms such as "more stopping power" and "less powder"...
Pain can stop people, (we include that in the category of a psychological stop - OMG I've been SHOT! it HURTS!! I'm gonna stop now..._ but its not what we rely on to stop dangerous animals or humans. We rely on physical damage.
Show us some numbers (even estimates) supporting these claims.
Give us your theoretical reasoning to help us understand how your cartridge manages to defy the laws of physics and meet the claims you make for it.
Show us the difference in case capacity between your wildcat and the 10mm Auto. Tell us your expected bullet weight, velocity range and operating pressure. There's no free lunch in firearms physics (or, anywhere else).
Taken collectively, the members of this forum have a few centuries of experience, and while some of us are grumpy old curmudgeons (yes, that's me sometimes ) a lot of us do know what we're talking about from real world experience.
Also, just FYI, the Coonan, the Grizzly, the Auto Mag, the Desert Eagle and the Wildey were all made to run cartridges with a 1.6" loaded length. Your 475 wildcat with a loaded length of 1.425" wouldn't be a problem in them for length, but width is a different story.
Everyone needs more stopping power than what a .45 ACP can deliver because people that are junked up with the right type of illegal drug will not feel any pain from your gun shots.

You need the .475 Punisher because it has more stopping power than the .45 ACP without the heavy recoil of the 10mm Auto.
It's less gunpowder than what the 10mm Auto uses.
