It could lead to some interesting conversations.
First of all, Rumple’s deathbed call to Belle opened Bae’s eyes as to the fact that his father wasn’t pure evil and was in fact capable of caring about someone else. It also revealed the fact that there was some part of him that wanted to be better than he was.
However, we still don’t have any reason to believe that Baelfire knows exactly what Rumple went through to get back to him. I’m not really sure how he’d react to the news, it’s a lot to take in, and so, so much of what Rumple did was dubious and downright bad. However, he did make a lot of sacrifices along the way as well. Belle knows about a lot of this, as well as how Rumple was willing to leave her in Storybrooke to find Bae. (I think we can safely assume that Rumple shared a lot of the story with her.)
If we got to see this play out, I’d like to see Belle sort things out in Storybrooke, end up in FTL and pick up Baelfire and then head to Neverland. Bae would probably be really confused as to why she’s going through so much trouble for his father, and we could have a warm heart to heart where she tells him that maybe he doesn’t know his father as well as he thinks he does, thereby opening his mind to some reconciliation.
