OK step 1 on this plan is to get involved in something that works in a similar way so you can get some perspective on the task you are proposing.

I promise you: the reason this doesn't exist already is not because nobody's ever had the idea.

For that matter, maybe it does exist. Step 0 is to find out for sure if it already exists, even if it sucks. Or if it ever existed. You'll want to know about that.
