One could either manually control the power split or devise a simple controller, perhaps via laptop that could read various parameters and issue the appropriate commands or some combination of the two.

That's roughly what Volvo is doing to its entire PHEV range, and Toyota does with 4WD versions of its hybrid SUVs, even though they also retain a regular hybrid setup on the front-end (with Toyota retaining the HSD, while Volvo resorts to a "pancake" motor between the engine and transmission) and just supplement it with the rear motor.
