One more thing I'd be remiss if I didn't mention - the drive modes are tightly integrated with the engine control. As the ECU modulates engine power and directs torque to each wheel, it needs intimate control over the engine's throttle, ignition, fuel, and more. Once you swap in a different engine, that all goes out the window.
Without access to Ford's software and engineering knowledge, it's unlikely anyone could cobble an engine in there and make everything work happily together.
