Arcane Crescendo.
First we need a set of psionic powers to use our pp on. The Shards of Leadership trick supplies this nicely, letting any character capable of acquiring a psicrystal ultimately snag every power in existence. That said, we have no pp as of yet, save the 1-20 from either race or feat(s). Enter mental pinnacle. We now have an assload, particularly with a high CL, and at ML equal to our CL. Now remember how we have all those powers? Manifest metaconcert, and if you don't wish to conduct it, pawn it off on your shiny pet rock. Congrats, you now have a massive reserve of powers known and power points disassociated with you, but no spells so long as mental pinnacle persists. Well, dismiss it. Remember, your power points are now in the metaconcert, so you have none to lose from ditching the spell (0pp-0pp=0pp). End result? All the goodness of psionic buffing and action rape on the chassis of a Wizard, without having the dicey mechanics and arguments involved with a Spell to Power Erudite, and better capability to optimize both sides, especially given that your only limitation to manifesting absurdly powerful powers is your CL, and there are a million and one ways to augment that. Oh, and ensure the metaconcert is capable of using bestow power, as even unaugmented, once you have those 2 pp back from it after dismissing mental pinnacle, you regain ability to achieve psionic focus, allowing the full breadth of action abuse.
