I don't really know the amount of work needed to do this, so it might be just a stupid idea, but would it be possible to add new tracks to the game, like Baku, Austin, Imola, the long old layout of Spa or even the Nordschleife?
that might force managers to adopt their strategies to the new tracks, and could piment the championnship.
If that makes too long seasons, there couldbe an option for each league admin to select the tracks used for the next season.
Once again, i don't know how much work it would represent, i just thought it could be fun, istead of revisiting the 2009 calendar times and times again
