Rikudou Sennin is an Uzumaki - this isn't fact, but it is the closest we can get before it is actually revealed or stated by Kishimoto to be true, so let's assume that the Rikudou Sennin is an Uzumaki alright?
Now moving on, this is where I go into why the Namikaze probably have more significance than we believe.
One major piece of information that shows that the Rikudou Sennin is probably an Uzumaki is in relation to appearece. Naruto appears a lot like the Rikudou Sennin, ecspcically in regards to appearence. Naruto appears most like Rikudou Sennin when in Kyuubi/Bjuu Mode. Obiviously there is some relationship and that must be because of the Uzumaki right! How about...no.
Naruto, forgotten by many isn't a pure Uzumaki. He is only half, with his other half pretaining to the Namikaze. That is where Naruto inherited most of his physical appearence from - facial structure, hair color etc. This is Naruto's PHYSICAL appearence. Naruto inherited his spirit and personality from his mother. This is Naruto's SPIRITUAL force.
The Uzumaki are a symbolification for SPIRTUAL energy while the Namikaze are a symbolifcation for PHYSICAL energy. Together they create the blueprints for a possible, Savior of this World.
Namikaze Ancestor + Uzumaki Ancestress = Rikudou Sennin
Rikudou Sennin + Hyuga Ancestress = Senju Ancestor + Uchiha Ancestor
I think that is something like how the timeline goes regarding the origins of the Rikudou Sennin.
