Hi, groovy idea for sure.
If users got rewarded for the class, or like if they pass the language test, they eatn coin... That could motivate a lot of people. Hmm. Or even just use hive as the main login for these platforms. Lots of great possibilities.
I don't know anyone at the places you mentioned, but happy to help if I can. :)
