Well, Combat Manifestation is an easy one, and so is Quicken Power. I guess there's no way to quicken a PsLA, so perhaps something like Twin Power or Psionic Meditation instead of Quicken SLA. Spell Knowledge can go to Epic Expanded Knowledge (can always reserve one for a different feat if we want). Improved Spell Capacity goes to Improved Manifestation (again, we can reserve one for something else). For the rest, maybe some metapsionic feats ending with Improved Metapsionics?
