Remember though, just because you haven't heard of it don't mean it hasn't been done before. Unless there is a distinct advantage in "wildcatting" something it can be an expensive and pointless exercise.
Just about every commercial cartridge has been "wildcatted", necked-up, down, lengthened, shortened, improved, etc within a couple of years of release. Some then go on to be commercial in their own right, .22-250, 7-08, .260rem to name but a few. ( Remington tend to pick up on popular wildcats)
Manufacturers do it themselves, .30-30 Winchester is derived from the older .38-55 for example. Make the new from something you already manufacture makes good commercial sense.
If you have bucket loads of old cases you don't use that you can turn into something that you can use then have at it.
There is an element of truth in that, and there probably is something almost the same as all my suggestions already out there. Often though you don't know its name!
Part of what is driving my desire for a wildcat is that with the exception of my 22cals I shot exclusively cast bullets; now at typical jacketed velocities that means a lot of the case is full of powder, but at cast speeds, you often find that a lot of the case is empty.
Cases like the 25-20 and 32-20 are good in this respect as you can pretty much fill them up! I am considering doing a 25-20 or 32-20 using a 1:10 twist barrel so that I can shoot a bigger bullets, but with the advantage of still filling the case unlike in the rifle version i.e 25-35 and 30-30.
However a 32-20 with a 1:10 would let me shot 100-200 grain bullets, but unlike the proposed wildcat 222 derivative wouldn't give me the option to push the big or small bullets faster should I want to. I guess what I am saying is that I consider the 222/223 case capacity to be a sweet spot "the goldilocks cartridge for my requirements". Only not if its propelling a 22 projectile, the bee or hornet would come closer to my unusual taste in 22 cal!
