I love this idea! As the original author of TBA webhooks, it's awesome to see people come up with cool uses for them.

I think you're going to have to build your own server somehow to receive TBA webhooks and post to slack. I say so because TBA webhooks just return the raw data associated with an event. It does not return a human-readable string about what happened. It'll be best to let end users (you) decide how you want your messages to read and to format them yourself.

That being said, I'll definitely watch what you do with interest, and hope that you open source it!
