Naw. Nami can't have a partner that always swooning over her. She needs a man that can also guide her while looking apathetic.
Sanji deserves better, or rather, Violet chwaaan is the best option for him. She's fine with his attitude, and find it funny too. If Sanji and Violet get married, Sanji will own the title of Mr. Prince legally this time

Violet is a princess btw.
