Marcus wants to do this during the Friday night qualifying session at the Concord national event, so there should be no test session worries.
The question is would NHRA let them do it? The Friday night session run order is determined by the early Friday session ... it is unlikely they would pair up. I think it is a fantastic idea, run funny car first Friday night, then top fuel, then bring back Force and Pedregon for the last 2 cars that go down the track after a suitable amount of hype and drama buildup.
We might start seeing fights the week before every race at a Bruton track as the fuel guys will hope they could get a $20K grudge match ... that's a lot of scratch for 1 pass ...
