Ignoring Sanji's bad relationship with his father and brothers, I personally think that he shouldn't just completely forgo his surname. Yes, the Vinsmokes have an infamous history, but it's Sanji himself who defines who he is. Not to mention if he sticks to it, it would show that he and Reiju, who he truly cares about, are in the same boat. And yes, I think Vinsmoke Sanji has a nice ring to it.

Except the Coby/Rebecca thing, you seem to make a lot of good points.
