Thank you for your time to answer and explain your situation.
For licensing, in my case I ended up with MPL 2.0. It's strict enough for my creation but loose enough to allow others to use it. Attribution enforced by the license is really something I'd like it to have. I could edit it but then it's a custom license that is untested and unproven (and couldn't be called MPL or any variation of that).
I'm open to cooperate and help making stuff that is useful for the community. Like these tools you spent a lot of time on. If I can help, I'm open to help. I want Ren'Py to succeed and I believe these tools help achieving just that.
If you ever feel like cooperating with something, I help with what I can. You can find me here or Discord or lemmasoft forums. I'm brunoais pretty much everywhere. See you soon 😉.
