Can't remember where it was, but someone uploaded a pre-built fully modded karryns prison which i think has CC in it, think it was in MODS, or requests.
Sorry i can't help more!
yeah use vortex its too complicate to manually do it if you dont already know how it works its very simple with vortex it does it for you and you can download the mods you want straight from the program
Nexus Premium is only needed if you need faster downloads (with a free account, download speed is limited) and to automate downloads when installing collections (with a free account, Vortex prompts for every mod being installed in said collections)
Since none of the mods themselves are on Nexus yet (not even a section) a free account is perfectly fine
