Even if I don't think they suggestion is going to fly, I compliment you on your presentation of the idea!
As noted above, the income discrepancies between teams makes this a really hard idea to implement fairly. I'd love to make money on ticket sales, but that's because I have a nice sized arena. But I'd want to play all my scrimmages at home against only the best teams who will draw bigger attendance numbers.
Maybe as a substitute idea for additional income, we can all have a weekly bake sale, or maybe a fund raising car wash...
