Forgive me for getting off topic, but I noticed that Archon's Wings could be replaced quite easily with a 4th-Level Spell from a 3rd-Edition supplement known as the Demon Hunter's Handbook. The spell is called Wings of Glory, and it grants flight at double base land speed, sheds light equivalent to a Daylight spell, and the wings grant you two attacks with a BAB equal to your HD (as Fighter), and these count as Holy weapons. Quite nice, though I cannot at the moment remember the duration of this particular spell. Probably 1 round or 1 minute per level.

Just throwing it out there, see if you like it or no.
