This kind of work has been done quite some times, Some russian guys have done really crazy stuff with Bosch motronic ECUs..
I have seen a Supra with a Bosch ECU, an additional ECU mirrored just for the additional 8 fuel injectors - total of 12 fuel injectors in the manifold and 2 before the throttle. But I am sure that if I give Hameed the parameters to work with and a test bench, he can do that in one machine and would be tapped and live.
