No aftermarket automatic transmission case is legal in Stock, or so I was told by NHRA, so I do not think that you could add an aftermarket bellhousing to a case with an integral bellhousing. Just have a good shop put the internals in another case. I have seen NHRA tech allow an aftermarket transmission crossmember.
