If I got an hour of notice before the race, that'd be about as much practice as I usually have before each race each week, so this would pretty much change nothing for me.

Sounds like a great idea for a closed league, and a nightmare of mishaps for something like SRS.

Quite possibly a nightmare! The point is that it would change something for you because everyone would have that amount of preparation instead of you playing catch up.
