There's any number of classes you could combine based on indexes. Granted, some indexes have changed recently, but I put together a spreadsheet a year or two ago that showed all the classes that could be combined. Could be quite a bit of heads-up racing. You could say something like HP/1 = all 11.15 index classes, HP/2 = 11.25, etc. -=shrug=- Since we live and die by it, I'd just call it the HORSEPOWER Series.

That being said, if you're going to do a single stand-alone event this year, I'd suggest just leaving things alone and running it like the US Class Nationals. Since everyone would be there, things could be discussed on how people preferred a multi-race series for 2010 would be run.
