A bit of Raw abuse, but can't we take Shape soulmeld as our feats, shape the meld, then train the feats away? The soulmelds should last until we either A Reshape our melds(We're not) or B get hit by Disjuct soulmeld/essentia.
Here are a couple of characters I did for a similar thing last yearish.
I think they mostly work with out their items. Main issues are incorporeals which they largely lost the ability to deal with, and the reduced AC and attack .
With out equipment donating 21k to an animal shelter for Summon Natures ally at level/2 swift action once per day, seems like a really good idea for how to spend money.
Equipment>Eggshell Grenades for Blindness, Marbles for a grease effect, weapon capsules for damage boost, anti-vermin candles, garlic, blind golds, filter mask, flotation bladder, 11 foot poles, listening cones, adamantine drill, mitheral grappling hook, and sun glasses
Had Birds Eye vestige going for scouting, they were immune to mind affecting and could see invisibility from being devoted to and Elder Evil, or had good will saves, could teleport from Blink Shirt, Iron Heart Surge I felt it was more important than WRT.
Picked up Imperious Command and the Zheratim levels with most of them.
I also traded in their souls for 2 bonus feats. Was looking at being tainted, but that appeared to have actual draw backs.

PA+touch attack with the boomerang, looses Psionic Meditation so its only on the first round.
