Great idea, but easier said than done. Consent, assets, tweaks, settings ... that's just the beginning. Then you have to get into the mind of the dev and try to expand on his work seamlessly. Here the dev did an amazing job of depicting an MC riding the invisible line between sanity and insanity - just a little nudge would send him over the edge permanently.
This was going great until the dev decided to build an entire town - probably with the aim of expanding the storylineby adding more characters and places - and ended up burning himself out. IMHO he would have done much better to stick with the motel and continue the story there, allowing the claustrophobic confinement to prey on the MC's mind. Even the homeless girl was unnecessary - his family was enough material for several more episodes (he'd barely touched on the elder sister). I was looking forward to him grooming his younger sister - more fooling around, helping her shave, etc.
All the best for your endeavour.
