May I suggest having this be done in github, that was we can track progress, share pad files, multiple people can work on it and push different versions as branches. It’s also got an issue tracker to track issues, and even offer a release section so we can have versioned releases, I can lead this if you want? I’ll create the repo.

Here’s an Example of a well laid out and organised Minecraft resource pack using github
