I was thinking earlier about a cool mode for sparrow racing.. you race on a track with pitfalls/traps, and after you die say..3 times.. you lose all of your lives and are resplendent in enclosed "bunkers" which are connected via teleported network. Your goal once eliminated from the main race is to try and attack the sparrows still racing. To make it less OP by using weapons like lock ins and whisper/whatever,you could be limited to scorch cannons or some other kind of map pickup weapon+the enclosed bunker design will stop you from actually entering the course on foot.
