The Laughing One
We're all our own problem!I think my biggest problem is the cyberpunk game I want to run is set in Night City and I really want it to be Cyberpunk 2020. I feel as though I'm pining for something that simply cannot be. i.e. I think I'm my own problem.

I'm from the Shadowrun side of things and have similar issues as you have with Cyberpunk. I do not like the new Shadowrun 'world', I would prefer to keep it 2050-2060. There were issues with the old rules, and issues with the new rules. So IF I ever run SR again, I'll disconnect the setting from the rules and even that from rules options.
So why not make a Night City guide for your players and yourself from the old CP2020 material and then search for a rules set where you remove all it's own fluff from and replace it with Night City? With PDFs these days that should be easier then ever! Heck, we're playing with Foundry VTT these days and disconnecting rules from fluff/adventures has never been easier!
Have you looked at the Blade Runner RPG by Free League? To me it's atmosphere seems closer to old CP2020, don't know about the rules though.
