Good luck with your game, but unfortunately it's not really LLM, is it? I fear you might not get much interest, for the reasons below:
We don't limit our signings to make it harder. The AI certainly won't be doing so.
We don't trawl around looking for players that "take our fancy". The guidelines have been polished over a long time to get where they are now, and "fair amendments" don't just pop up on a frequent basis.
What does custom tactics mean? Anything non-default, or downloaded?

Either way your statement is incorrect as almost all LLaMas use custom tactics of their own design.
In LLM, the aim of the game is to have fun while playing 'realistically', not to keep a scorecard.
Anyway - have fun, but like I said, I don't really think this is LLM. You'll probably get a better response out of the stories forum than in here.
