Unfortunately I don't think it would quite count if we pretended other letters exist. In RWBY, they're all pronounced as they appear. RWBY, ruby, JNPR, Juniper, CRDL, Cardinal. The words they make all begin and end with letters in the team name. 

AMON is an Egyptian spirit/god, so if we kept with the letters we have, we could use that and it's kinda cool. Otherwise, I think we'll need some new letters.

I know Hero is willing to change Odette's name. Lugubrious, are you at all willing to pick a new name?
