Haven't tried it yet but going to give it a shot, it seems like an interesting concept. What I'm reading states you started to make it for yourself then decided to change that focus for some reason, this is your story so get it out and see where it goes. W.M. here posted a review and I got the notice so it's worth a shot
If you want to do something like that in the future go for it. I have no problem with derivative works or works based on my idea. Of course giving me credit for my part is also appreciated. Like I said I just have no motivation at the moment. If that changes I will see where that inspiration takes me so feel free to run with the idea if you want.
