Dual drive running order: Don't you think this is all getting a bit too serious here, for something that is meant to be fun? There are far too many variables involved to say that the second driver has an advantage because of the tyres being warmed up by the previous runner - weather, incident delays, class size, etc... Next you'll be having Official Tyre Temperature checks carried out at the start just because it was sunny one minute and cloudy the next. I think you're trying to 'level up' a small bump in the road, compared to something like the extremes of engine power output in a single class.
