Those are all serious concerns, and I expect PHEV vehicle design to change over the next few years (my only concern is how many “few” is).
The more sensible design if you’re are going for ‘ICE as backup’, not ‘electric as efficiency improvement on top of ICE’ is a typical electric ‘drivetrain’ and battery, with a generator, more similar to diesel-electric trains. A switch to diesel in general wouldn’t be a bad idea either, but the north american would be resistant.
Depending on how gas proces and the EV market go, I wouldn’t be surprised if drop-in engine replacements for converting ICE vehicles to hybrid become easily available in the next 5-10 years either, especially on larger vehicles
