Let the players make the rules
Every summer, the players get together to decide the rules for next season. During their process of debate and deliberation, former players and coaches (and refs, etc) are allowed to advise the players upon request.
I think this would be a mess for a few years - which be entertaining in its own right - but eventually through trial and error the players would be able to find the best competitive balance with the rules. The floppers aren’t going to be able to justify their bullshit to the other players if they have to say it out loud. They would also be able to address block/charge, balancing offense/defense, etc. They love the game and want it to be fun and competitive.
