Isn't the real core of the solution in the PCM (ECU)? I get it that the immobilizer is in the path but a failed ECU still spells the end of the powertrain regardless of the skreem or key RFID. I'd love to jumper past that little box and have an ECU that is only looking for a circuit to be completed from an ignition switch - like the good old days. I acknowledge that I'm ignorant here.

In any event, I'm interested in contributing $$ if there is some evidence of hope.
