I'd considered running an electric motor straight into a traditional gearbox's input shaft before, but running it between a gearbox and an ICE adds another layer of complexity. With no clutch at all, I suppose the engine is spun up by the electric motor as the car moves off, and stopping involves going into neutral? Likewise moving off once the engine is running would require rev-matching and floating into gear (or with a sequential dogbox, just harshly banging into gear).

For the 4WS system there are lots of OEM options for electrically-steerable tie rods, Honda used them in some Accord models and Porsche has some as well.

Why take it in and out of gear?  Just let the electric motor handle smoothing out the transitions.

Let the clutch pedal act as a switch to indicate to the motor controller what's about to happen.
