Yes, it has been done. I recently broked a 20VCQ which had this setup running. There was just a few differences from the standard. One difference is distributor - it is combined from 20V and KV in one hybrid, second, like msh said the injectors need adaptors, because you use your standard injectors from atmosphere engine. All in all that's it. And yes, ex owner said he had big petrol consumption - lake mode, thirty minutes equals in thirty litres of petrol.
If you need I have that distributor spare and lying around.
