How about mixing in the 125 2-strokes with the 250's as well? My issue is similar, with a 160 4-stroke, Triumph 800, and RS125 2-stroke single all of my potential race entries would only be competitive in the same class. I am up for adding another "spec" class, but nobody even has one of these that I know of? Why not cater to the bikes we do have, or be sure that enough interest lives in people WHO WILL ACTUALLY GO BUY/BUILD a bike?
