Wasn't that Fëanor's point?

Anyway, as to the original question, I think Finarfin retained the kingship of the Noldor in Valinor and would have done so even if Fingolfin had been rebodied. Why? Because I don't think Fingolfin was the type to have demanded things be otherwise. He would have readily admitted his mistake in following Fëanor, and would not have allowed himself to claim the kingship because of his past deeds, thinking himself unfit to rule over Finarfin, who was also a son of Finwë and had taken no part in the deeds of the Noldor which had led to the Curse.
