I don't see the control system as being that difficult a hurdle.
After all, the Harrier is able to hover with only two nozzles.

I think you will find that the Harrier has four main swivelling nozzles,
the front pair are cold air from the compressors, the rear pair are hot
exhaust from the turbine. In addition it has air driven control jets at
nose, tail and both wing tips. All of then are required for hovering
flight.

I've not noticed any other Harrier nozzles than one on each side.
Thanks for the information. I suppose in theory it would be possible
to hover with only one nozzle.
