Is there any psion variant/ACF/etc that gets Grip of Iron?

I have a character who would really like to have grip of iron, the 1st-level psychic warrior power. However, said character is a psion, specifically an egoist, not a psychic warrior, and doesn’t have a feat to spare for Expanded Knowledge.

Is there any variant, ACF, etc. that allows a psion to learn grip of iron? All 3.5e material (including 3.5e-legal 3e material) in Wizards of the Coast sources or Dragon or Dungeon magazines are acceptable. Said variant cannot touch the 1st-level bonus feat, as I am already using the variant shapeshifter egoist to get minor change shape instead of that bonus feat.
