Counting as a 4th Level Cleric or Paladin?

[ATHATH]

Is there any way for me to qualify for the Initiate of Amaunator feat without taking 4 levels (a dip is fine) in Cleric, Favored Soul, or Paladin or taking levels in the Rainbow Servant PrC?

Some relevant text from page 15 of Dragon Magic (thanks, Thurbane!):

Any character of a class that must select a deity and that uses the cleric spell list for spellcasting can treat his level in that class as if it were a cleric level for the purpose of qualifying for an initiate feat.
Isn't there a Wizard ACF or substitution level that forces you to choose/select a deity? Note that the text says "select", not "stick with" or "worship", so theoretically, having to choose a deity to swear vengeance against or something would work (although that's not part of the ACF that I was half-remembering).

The wording of "uses the cleric spell list for spellcasting" might be abusable.

1st party and Dragon Magazine material is on the table here (while homebrew and KoK stuff is not), by the way.

Not quite, but perhaps they could work.. Divine Crusader and Apostle of Peace?
Nope; the feat explicitly requires 4 levels in either Cleric or Paladin.
