[Song of Ice and Fire] Could Ned Stark have gotten a writ of legitimacy for Jon, just to be nice to him?

Catelyn Stark specifically forbade it. Jon Snow posed a risk to the integrity of House Stark and as an extension the integrity of House Tully as she was the oldest member of the house after Blackfish(who never married) and her younger brother in succession.

If Jon was made legitimate and Robb Stark died as could happen easily in the world they live in Jon would inherit House Stark and her legitimate children wouldn't.

Eddard who had almost no political mind didn't understand that and asked Catelyn anyways.
