All I want of an electric upgrade is to top up my traction battery, so I can start the car with it 100% charged. Then I wouldn't suffer the mileage penalty for the warmup period because there wouldn't be one. I drive 5 miles to and from work. For the first couple of miles, I get about 25-30 mph as expected. If I reset the meter then, it is easy to log mid 40s or even a 50 or two. Is there anything out there that does this, hopefully with fewer mods (and less expense) than a complete PHEV conversion.
