Aside from Gold Cup, where else are 4-Cycle racers racing in the area?
IMO, unless the clubs in the area have good numbers, there is no reason to add another series to the already packed program that is Midwest karting from April to September.
Michigan has very little in terms of numbers with only two tracks. Ravenna has all kids, and they all race Clone with spec rules. They get maybe 40 racers on a good day total. East Lansing is about the same in terms of numbers.
If you create a series, you just pull away from the clubs. If you are looking for a series, I would just support the Gold Cup for now.
What about a big 4-Cycle Midwest Nationals event, three days in the summer at one track, include Clone, LO206, and Animal classes.
