Battery tech will need to improve greatly and be minimalized. EV batteries are currently massive, heavy, and generally engineered as long, wide, flat modules to be installed beneath the floor so they keep the center of gravity low and the vehicle balanced. That's not really possible in an ICE vehicle with all the frame molding around existing exhaust and drivetrain components, and you most likely can't just have some sort of modular battery and motor unit that you just drop into the engine bay, as that would put a ton (literally) of additional weight on one end and mess with the balance.
The draintrain components may need to be replaced or the motor outputs modulated to prevent the torque from ripping it apart.
Power steering and brakes will need to converted to electric assist. AC and heat would need to converted to electric.
Older cars (early 00's and older) with cable throttles will need to be retrofitted with drive-by-wire, or use some sort of adapter module that connects the cable and converts it to digital inputs. Same with brakes.
All of the electronics (lights, wipers, windows, locks, radio, etc.) will need to be rewired since there's no longer an alternator.
Probably will need upgraded suspension and brakes to handle the extra weight.
There's probably a lot more I'm not thinking about or not even aware of. Unfortunately, I don't think it's going to happen outside of rich enthusiast circles, which is terribly sad, because I completely agree with you. Basically everything made after around 2010 is total dogshit.
There are likely a lot of complexities here.

Aaawwww Man. I hate to admit it but you're absolutely right. It's so much work it might not even be worth it.
Spaßbremse!

Reality is often disappointing
It is, depending on the expectation
