How about making it happen ?
getting past champions to race in low buck bomber type figure 8 cars. Each driver builds a car that he races in the first and last race of like ten races during the course of the season, the other eight races they race one of the competitors cars, each driver gets to race once in all the cars.
Maybe S.A.F.E.R. can get sponsors, there can be points each week. Winner takes all, and at the end of the season, the winner can donate the winnings to a charity.
Maybe we can throw this around, iron things out and each year have a champion's champion.
