It seems to me that nearly everything that needs to be done with a whisper cartridge can be done with a large-bore handgun cartridge, fired at subsonic velocities. A 44 magnum, 50 AE, and 500 S&w can all be loaded to subsonic velocities using heavy bullet weights, so why reinvent the wheel? I'm missing someting, so fill me in. I suspect it may have something to do with compatibility with the AR platform, but if you can adapt an AR to fire 22LR, you should be able to adapt if for the cartridges mentioned above. So fire away; what is so special about the 300 whisper, 338 whisper, 6mm whisper etc?
