Hmm, I don't see why not, The Initial Mod and Subsequent Update will focus on some problems people have with the base game like lack of dialog, events, interactions besides training, selling options, and some additional things for slaves to do once trained. And a retooling of the training system to be less monotonous and one note.
Afterwards I will mostly be listening to feedback of what people in addition to the working on the bigger things I want to add to the game. so since you asked I'm happy to add it to the list!

It may not be in the first two updates depending on how much will be needed to change mechanic-wise and the scope of what people would like to see but I am happy to add something like that
If you don't mind me asking, what sort of things would you like to see with bigger size dicks? Like it being used a fear or humiliation tool? I won't promise the impossible but hearing what people are interested in seeing is good and I will do my best to get it working somehow lol
PM or here is fine with ideas, but PM might be better to talk about specifics and details!
