Maybe.
Although he does have other stuff in common with Akatosh then just looking like a dragon. They also both have spheres dealing with order. Time is a form of order (hence why Auriel is the soul of Anuiel, who is Order), and "Peryite, whose sphere is the ordering of the lowest order of The Oblivion."
Also, "Ruptga was so big that he was able to place the stars in the sky so that weaker spirits might find their way easier."
"Ordering of the lowest order" vs guiding and "keeping track of" the weaker/lesser spirits. I think it's at least a potential connection, plus it says that Peryite used to be an ehlnofey (if I'm reading that right).
And just for kicks, they also both have seven letters in their names.
