Interesting suggestion but I prefer mine.
a tanking/staying lv team cannot play CL/SL or Cup the next season.
The reason I don't agree with the suggestion above is that we might see tanking teams reaching the final and then loosing on purpose - lol
Meanwhile, they will destroy other "normal" teams going for a title.
The best is to have an option to declare that your team is only for associations.
no CL/SL, no Cup, 0-3 to every League game (or not placing at all in a League table).
Another suggestion I made is to play in associations with our secondary team, the national team we had and leave the club out of FA.
