Okay just gonna throw this out there since I don't know how no one has copied me because everyone spams fb dive conversions and I've been doing this for 4-5 seasons across multiple leagues, but you can stop the 2pt conversions at a decent clip with 1 rule and 0 overrides without relying on glitches.
Just make a rule to run 4-3 Under Double LB Blitz against 2 pt conversions and you will stop >50% of them, making it worse/equal to an extra point. The first time I played Smirt in D&D I noticed he ran the 2pt conversions and literally just looked for a play that looked like the LBs would be in a good spot and it worked.
There are probably better/more consistent ways to stuff it but this one is easy and requires almost 0 effort.
Problem solved.
