It would make him more cunning. Growing up among the Lannisters would force him to be on his guard all the time and develop ways to outwit his opponents.
His character would become more complex. On one hand, he'd be influenced by the Lannisters' ambition and power - hunger. On the other hand, his Stark roots would still be there.

The Lannisters' values are different from those he was raised with in the North. This could lead to a conflict within himself as he tries to reconcile his Stark upbringing with the Lannister way of life. He may also discover secrets about the Lannisters that could change the course of his future and the future of Westeros.

It might be that Jon Snow, while being fostered in some new place or by someone new, gets involved in a situation that is both challenging and has a touch of the 'lemon' nature.
