Yeah, I know, we have already discussed it somewhere. BJ said Kys Töff might still work on it - I'm afraid we won't have such a complex event in the future.
What about a simple NFS-like "Factory Driver" contest, where you do not race against other pipsqueaks, but you have to complete different exercises? There would be a minimal criterium in each rounds and you could collect bronze, silver and golden medals with your exact performance (e.g. bronze medal with 10-12 jumps, silver with 13-15 jumps and gold with >15 jumps in a minute). It could be a permanent event with a ranklist.
If it's worth to start such an event, I would make at least 50 rounds.
sounds like ZakStunts 2007. It did not work out well, but it may work for you. I like special rules.
