Personally having the ability to take from shitty guys would be a good content choice. If you act horribly maybe you get what you deserve. Flip the overused trope of the black guy being some meme tier character and have him be a "good" guy.
We have so much NTR content being copypasta it killed any vibe I get from it anymore, so having it be one of those "deserved" situations based on player choices (maybe a bad end for old man trying to creep on the cop too much or if there's any sort of blackmail content, not having the cop on your side = bad end as they report your ass) would be refreshing. Shota getting dommed by the cop/some other character who want him for themselves as a bad end (little shit thought he was going to get a harem and rizzed up the wrong person for that
), maybe one of the characters is a yandere, maybe one of them has an old man fetish (and will actually pursue the old fossil).There's a lot of ways you can do it to make it interesting and not rely too heavily on already heavily overused tropes which will even pull in people who don't typically like multiple protags/etc type content. Make some types of content in the hands of the player via path ("bad" choices) other than just "it happens."
Things like that which again make it realistic that perhaps one or two characters are not possible for a harem and/or are bad ends if pursued will really help at reducing your workload to have EVERY character availible, especially if you're already significantly increasing your workload by having multiple protags. Worst case you can always add on such content later on when you've got the main part of your game done or close to it. Nobody ever said a dev can't do afterstory/what if stuff later.
