Cherry Picking/Merging Two Images

[area51cortland]

After numerous hours fumbling my way through building, refining, and tweaking my image (#1), I've outgrown the 32gb micro SD and will be getting a 64gb. I'm writing a cleaner and more functional totally different 32gb image (#2) onto my new 64gb card, but I want to salvage from the one I built. I don't want to screw this up. Any answers or links to answers would be greatly appreciated.

I'd like all the "ports" (BG1/2, IWD1/2, Dooms, Quake, etc) from #1 onto #2. Is it safe to just straight up copy/transfer everything inside \RETROPIE\roms\ports on #1 to the same on #2? If so will I have to go into the experimental packages and install again?

Will copying any particular files cause any conflicts on a different image with different configurations (if that makes sense)? I added in some overclock settings and tweaks to make N64 play smoother. Are there certain files I should copy over to get those settings or just redo them?

I spent a lot of time scraping nice 4img scrapes on #1, but #2 will have at least basic scrapes for everything. Are scrapes keyed to very specific file names or the renamed post-scrape metadata name that shows up changed in ES interface? Would I be able to dump my #1 scrapes into a #2 folder and overwrite the existing ones without complications? What folder(s) would I do that with? What about metadata?

This fresh install might help with my PS4 controller situation. I defaulted to using a cable because neither the basic bluetooth connect method or the ds4ps method worked. One connected, but had errors and did not allow me to set buttons and the driver was not very responsive or working well and kept popping up a weak signal message. Any tips?

Sorry about this being so long. I just want to get this right so I can actually sit down and enjoy the system instead of constantly tweaking it or working on one emulator or settings or another.
