I'm against this to be honest.
Imo the kink of this game is that we get to abuse the heroines themselves and slowly corrupt them into sluts. If you are allowed to create clones, then the kink disappears, because it would be no different than renting out your car.
i dont see how my idea contradicts this. you will still have to do that in order to raise funds. but right now, if you waste all the money you have, and need it for a new character upgrade or contracting a villain, you gotta re-lock the heroines, to send them to work, lose their access in the rooms, get the money, waste it again unlocking it.
similarly, you are not forced to do it, its an option that would work as a money sink/QoL for people who dont want to do that, or use the cheats.
it would also work as a natural progression of the gameplay, that more people would be willing to engage with, since it would translate into actual gameplay choice.
