Interesting idea but I don't think it really fits what Joplin does. Joplin, to my mind, is more about being able to take note and create records of things, interactivity comes second I think...
Although I would suggest you look into Anki (https://apps.ankiweb.net/) which is a flashcard application in exactly the style you suggest with many different styles of QnA cards, tagging/filtering, spaced repetition, etc. I used it in my undergrad for ages and it's pretty great!
There have been calls for an Anki plugin in the past here and here but the plugins seem to be dead, you could see if someone is willing to make a new one...?
(On that note @tessus the hopepage for the plugin "Joplin Anki Sync" in the plugin list 404s, might want to try contacting the dev and see if it's been abandoned)
