Before I go back lurking!!
Is this already not part of the Club rules??
As listed here:

It has the definition of the Formula grades.
So is it not possible (including / excluding motor type) to have an F5 Champion, ie driver in first year, F4 Champion, experienced clubman, then F3 Modified and F2 Modified.
No point in re-inventing the wheel if it is already there.
The race computer can assign people into heats as per their 'F' grading.
