I voted 'yes'.
It might be a bit too wicked an interpretation of the question, but the moment I knew O-sensei created aikido for a large part inspired by his religious beliefs, religion became part of what I thought of aikido.
So yes, religion should play a part, in my opinion every aikidoka should have some notion of O-sensei's religious beliefs (e.g. Omoto-kyo, 20th centruy, lots of kami). What they then do with that knowledge, is entirely up to them.
Of course O'Sensei didn't really "create" Aikido, but evolved it.
