Admittedly i answered the question purely on a footballing basis.
I believe that these rules could be implemented gradually over the course of say 4-5 seasons also the rule would be announced a few seasons in advanced to help clubs adjust.
This rule would ideally help the national team as...
Id also introduce a rule something along the lines of:
Each MatchDay squad has to include 6 English players. Each staring 11 has to include 4 English players.
Each MatchDay squad has to include 3 players that have come from the clubs youth team. 1 of which has to start.
Retrospective bans on diving/cheating.
FFP penalties that are bad enough for clubs to follow the guidelines
And generally refs being tougher on everything. Wouldn't take long to clear diving out the game if punishment was properly introduced
