If an appropriately preserved but soulless clone of oneself is available—probably created through the use of the spell clone but maybe generated some other way—is that body a valid target for the psionic powers mind seed, mind switch, true mind switch, or similar effects? The entity may or may not be the originator of the clone.
This Doesn't Work Directly
Clone Grows a Body Without a Soul
...A duplicate can be grown while the original still lives, or when the original soul is unavailable, but the resulting body is merely a soulless bit of inert flesh, which rots if not preserved...
Mind Seed Uses the Target's Soul
...Although the subject starts off with memories of your experiences, it possesses its original “soul” and physical body and is free to develop its own personality based on its own new experiences...
Mind-switch Targets a Living Creature
You can attempt to take control of a nearby living creature, forcing your mind (and soul) into its body...
Polymorph Any Object To the Rescue!
As with the Psionic Sandwich, you can PAO the body from a corpse into a living creature, mind-switch, then dispel the PAO. PAO it into a shrieker or other immobile creature, first, then manifest dispel psionics, as per the sandwich (or merely wait, immobile, for 3 hours for the PAO to elapse). The clone now has your soul and mind in it now.
Even this might not be enough to animate the clone; the spell only refers to the original creature's soul, not adding in just any old soul. I'm unaware of anything that fixes this, but...
Stone to Flesh Works Wonders
Stone to flesh sets precedent, which I'd say allows you to bring that there corpse to life.
Creating a corpse via stone to flesh is faster and cheaper, and actually talks about a life force being available to animate the created flesh. Consider just using it to make the body, in conjunction with stone shape or fabricate.
The best way I can think to do this is to stone shape/fabricate a beautiful statue, PAO it into that shrieker (it's a creature now), mind switch, dispel/wait, then you or a helper cast stone to flesh. Order matters here; your mind should be inside the stone before you make into flesh, as that's closest to StF's phrasing
Such flesh is inert and lacking a vital life force unless a life force or magical energy is available...
Spell to power Erudite can manifest Sor/Wiz spells, so can PAO, fabricate/stone shape, and stone to flesh. But he needs a way to Still or Silently cast them, if he's doing this to himself.
