Just make two mod folders, keep on desktop in folder marked PatreonWW and the other in a folder Marked PublicWW I do something like that myself, and it sort of works. I just swap out as needed.
I think I just keep like The CNWW stuff with the Public WW in one, and what ever in the other. The Nisa, and basemental don't care which one they work with so no need to move them around.
I don't move them I just delete as needed from the sim's 4/mod folder, and copy and paste as needed to the Sims 4/mod folder.
EDIT >>> Might seem troublesome, but it a lot simpler than making a new character, and adjusting there body, make up, eyes, skin-tone, and all there clothing.
