Respect for taking the initiative to try and pull something together.
My suggestion would be to take a look at the midwest based “LO206 Cup” for ideas. Their program is based in the Midwest and seems to be working very well. They have support from Briggs, a rulebook already done which accommodates both CIK and WKA bodywork and have a spec tire picked out with support from Vega.
