I agree, if it were me attempting this, and I may for Chopper Nights, I would retain the front frame headtube, downtube, seattube and BB shell. From the rear frame, keep the rear triangle, seattube, and BB shell. New tube wise, fabricate a diagonal, toptube and bottom tube.
Done with some care, the Diagonal can be slid onto the fwd seattube then mitered. After that the bottom and top tubes can be mitered then weld slowly and constantly check alignment.
Getting real creative, lager thin wall tubes can be purchased and have the end reworked / reshaped with heat and some coaxing. Even the bottom tube could be modified from round to oval with some careful press work.
