The final question is simply one of "why would you want to?". In return for a large capital outlay and increased maintenance costs you would get a small improvement in fuel consumption and a claimed reduction in the risk of in-flight failure.
In my case I didn't actually want it, but I did want that particular mark of Autogyro and the previous owner had fitted the system. I decided that it was worth putting up with the disadvantages rather than revert to carbs
