i'm not so sure about this. take a look at the first game and bastila who was removed early yet her connection to her family is still rather strong. it simply provides more training in how to handle the emotions since the force is affected by emotions.
What is truely needed and it would be nice to start seeing it in perhaps the third installment is other perspectives on the force and people who use the force other than the "jedi order" or the Sith. the two make things overly simplistic when far more detail would help the story.
A Jedi perhaps that uses his or her emotions to fuel their power but arn't automatically evil. Willingness to fight or to attack to defend someone isn't automatically evil nor is it good.
ultimatly expanding the jedi mindset and various types will help with this.
