Constrain "Legitimize self" decision for cadets

Hi,

So there is this legitimize_self in "Crusader Kings II\mod\A Game of Thrones\decisions\minor_decisions.txt" which allows a character to legitimize himself/herself when he/she is independent.

It seems to me the set of constraints is a bit too loose in some cases.

Indeed, I think the head of a cadet dynasty, should not be able to legitimize his/her cadet house unless there's a limited number of generations between this character and the founder of the cadet house (close kinship).

I'm no CK 2 expert but I'd define close kinship as the difference between the big red droplet on portraits and the dark smaller red droplet.

To give this a bit of perspective and a use case:

Thanks for your time and consideration
