IMHO, I think that this is how it should be structured:
- 1 Championship- This will look very similar to the current championship.
- About 4-8 Super-Districts. These will be a bit bigger than the current districts, though about half the size of the proposed super-regionals. Each sends the top few dozen teams to champs.
- Competitions- these can be similar to current districts, though the whole super-district would be open.
- The top 50-100 teams in each Super-District can go to Super-District Championships.
- International teams continue with the regional system until they have enough teams to create a super-district.
Pretty much it would take the current district system, and make each district bigger. Having fewer districts allows FIRST to concentrate its resources in fewer district championships, and this system only requires 3 levels instead of 4.
