Repowering and sharing fossil cars

I recently learned that Vauxhall (they are part of a conglomerate including other brands) are thinking about giving up car production in the UK due to the "mandate" which requires 20% of its production to be EVs. The problem being that demand for its EVs is not sufficient to enable the company to produce ICEs in the numbers required for profitability. I have written an yunpublished letter to the press (The Guardian), to Citroen (the make of car we are driving) and the Society of Motor Manufacturers and Traders (also with no reply) suggesting that a whole production line be dedicated to the re-powering of ICEs by replacing the petrol or diesekl engine with an e equivalent and battery. This would save scrappig the chassis, wheels, windows, body and upholstery. I estimate that giving this job to one of the smaller ans specialist garages would cost far mopre than the car is worth. Doing the job at scale could be half the cost and much cheaper than buying a new EV. Please tell me if I am wrong about the benefits that could be derived from this approach to electrifying road transport. Buses, trucks and dust carts are already being re-powered but it would but affordable re-powering of cars would have far more impact. If this would just sustain car dependency then please ignore this blog. I actually hope that other measures will assist in the change from individual car ownership car sharing of many kinds.
