I think this is an interesting idea. I could see it being kinda fun but I don't think it should be a minigame on the server. It seems to me more like a lobby thing. It should just be on one map in the lobby and you could win prizes for completing it based on how many of the targets you go through or something.
It would be pretty useful for learning and mastering the grapple.
