If you try to qualify with the Psychic Warrior, you eliminate the multiple stat dependencies. (Both cast with Wis)
You can qualify at Cleric 3/ Psiwarrior 4
Before going in you have BAB +5, 7d8+con Hp (Average 35+con) Base saves: +7 fort, +2 Ref, and +4 Will
At the end of 10 levels of
Psionic Theurge, you:
gain +10 d4 hp, +5 BAB, +3 Fort, +3 Ref, +7 Will (total: +10/+5/+11)
You can cast 7th level Divine spells, and manifest 5th level Psychic Warrior powers.
It's not The Most Horrible Thing Ever (tm), but it's interesting
Now, if you do stick with Psion (or Wilder, since Cha helps Clerics too), you'd have great will saves
![Devious :] :]](http://www.enworld.org/forum/images/smilies/devious.png)
, qualify one level earlier (which means you're not losing anything on the +1/3 levels saves progression) and could qualify for the
Arch Psion Prestige Class
But if you were going to do that, I'd think you combine Psion/Wizard or Wilder/Sorcerer with cerebremancer and mix and match Arch Psion with Arch Mage
By the way, Psionic Body combined with psionic feats easily makes up for lost hit points
