This is not so pashut. Is Eliyahu Hanavi considered to be alive?

This may be a machlokes the Rambam and other Rishonim. The Ramabm was
mechadesh that if all the chachmei yisrael in EY get together they can
be mechadesh semicha. A number of Acharonim explain that the Rambam
was bothered by the following question. How will the Sanhedrin be
reconstituted when moshiach comes? Who will give semicha? Therefore he
came up with his chiddush. Why not Eliyahu Hanavi? He was a samuch and
he will herald Moshiach's arrival. It would seem that the Rambam holds
that Eliyahu Hanavi is not considered alive and could not give
semicha. If that is the case then anything he teaches is "lo
bashamayim" and not part of the mesora.
