The Keizer-System for Club Tournaments

#1 I am a great fan of the keizer System and I'd love to see it implemented in lichess. During the pandemic i missed it a lot. My idea was to create a tourney to be played once a week in which those who wants to join just need to login the tourney page and say "hey, I'm available to play right now!"
I managed to implement my idea but with an external tool, in my case a great piece of software named "Sevilla"
Having such a pairing system implemented in lichess would be great!
