If we were to limit ourselves to a character's first names - at least those who adopted a code name - I thought of a few from your list who meet the criteria. Ororo for Storm popped out without conscious thought, and after a bit of consideration, Bruce for Batman, Barry and Wally for Flash, Hank and Scott for Ant-Man... there may have been some I missed.
Edit: My brain was still in the process of turning itself on when I wrote this yesterday morning, and I should not have included "Bruce" as an example. *boggles at self* I may have been thinking of Dick's brief stints wearing the cowl. Whoopsy!

Ororo definitely qualifies, and it's interesting that she has the same vowel-profile as her code name!
