It is kind of difficult to understand what you mean since you are obviously not a native speaker, but probably you want to play the complete street prostitution (the fallen path) branch from all episodes separately, that is, without playing other events, like a separate mini-game.
Yeah, it certainly would be nice, especially considering that that branch doesn't make much sense when Monica has other means of making money, such as working as the head of the escort service.
But I doubt that someone will make such a mod, least of all Decent Monkey. It is quite a bit of work. Well, maybe if the rest of the events in this branch are super awesome...
I would also like to see that, maybe even all branches like that. Probably in the form of a visual novel without too much clicking.
I wonder whether it would be possible for Decent Monkey to sell such a minigame on Steam. Call it something like "A Lady Fallen from Grace". That way, the ban of the Fashion Business that he received in the past won't matter, since it is a different game, will it? I would buy it myself. It is interesting what the developer himself thinks about it, after all he is lurking somewhere here.
