check out the BB fan art thread, there are people doing exactly that through renders, mods, and I think I've even seen a couple of people making their own continuation to the game.In my opinion the least he could do is make everything open source and put it on github or something, so if anyone ever wanted to continue the game they would be able to.
BB had some weaknesses, but it also got a lot of things right. the tease, the tension, the infuriating enemy eric, the stern mom. a lot of the people who dismiss it or try to make their own copycat game fail to understand those aspects, they think BB was just a room clicker with a douchy protagonist. and that's why their games can't make tens of thousands a month.
what pains me though is that it could've been so much better with a very small effort. the sex scenes were awful, cold, mechanical. and all the interactions were so cold, I don't think any of the characters touched each other once except to grab a dick. there was always this lack of warmth that told DS had no interest in it. (he also said many times that he doesn't get the incest fetish at all).
