No, the Magnum bellhousing - and we're talking about the AX-5 / AX-15 Dakota bellhousing - is unique, and won't fit any other type of transmission. The Aisin-Warner trans pattern is unlike anything else in the "normal" transmission world, and uses dowel pins to locate the bell on the trans. See attached pic.
The Viper T-56 has it's own funky partial bellhousing, and the GM F-car (Camaro/Firebird) T-56 is GM-specific. You can run a GM to Mopar adapter bellhousing that would do the trick, though.
The TKO (as far as I know) uses a "normal" round input bearing retainer, but you'd have to match the bell depth and bearing DIA to the trans, and the Keisler bell is the only one I know of that makes it a bolt-on. I don't think there's any magic in the process, but they have done all the leg work to make it happen.
The big things with all these units is that they will require some surgery to make them fit.
