Most of this sounds good, but honestly, making a SFW version sounds like a lot of effort for something that very few people would want. This is of course just my opinion, but I'd rather you spent your time adding content to the game.
I have always advertised Harem Hotel as an Adult Visual Novel, which is an Adults Only (AO) book, played in a video game format. Or an interactive comic book. Most people only know Mature/R rated media, then porn. Nothing in between. But life is full of nuance.
I can understand the confusion but it's not so black and white. Sex is a huge part of harem hotel, but it is not the reason anyone keeps coming back, and it isn't the reason I develop the game.
