Another noob question

[LOka]

So I am playing as Robb in the ACOK timemark. I marry Roslin Frey but Jeyne has a bastard by me. Fine, I acknowledge him and raise him as Eddard raised Jon. My bastard son turns into a brilliant commander with green dreams and his son (who is set to inherit Vigiliance - The Hightower Valyrian sword). So I give him a Cadet house cause his awesome, it's going to be intresting so see how he does.
However, now that I have a legitimate son my bastard will inherit The North because he gets the letimized bastard trait.
Is there anyway I can remove him from succession? Console command maybe?

TL;DR
How do I remove my Cadet-legitimized-bastard-son from succession (WITHOUT killing him)?

 

[Moarice]

Remove the legitimized bastard trait through console and add normal bastard trait.
Add Disinherited trait via console.
Send him to the Wall.
