King Arthur to Valinor

[Dûrbelethwen]

I was thinking about how at the end of the book that is the official Arthurian legend, a wounded King Arthur got onto a raft and floated downstream to an island where he was healed and I think he decided to stay there. (In old versions of the story told by the Saxons they were hoping that someday he would come back and drive out the Normans but that ended as the society became more intergrated.)
I bring this up because how some have made a connection between Merlin and one of the blue wizards. Do you think that there was some sort of connection between Valinor and the fate of Arthur?
