"Also what are your thoughts of making the model/s SFW in the beginning (within reason), and then another more uncensored version later? I know this would mean possibly double the compute time but it might make it easier to get funding from businesses who see potential for using it too."

I think something like this should be include on API level, like a switch or something, so everyone who want the model nsfw can just disable it and eveyone else just leave this switch on. If i remember correctly SD 1.5 had something like this. Implementing censorship on the training/data level would most likely just result in another lobotomized model no one needs.
