Fools... the answer is obvious... adopt Expanded Psionics to be the "spellcaster". You'd keep all the wizard/sorcs weaknesses (i.e. arcane spell failure) and the spells they would cast would be based on the powers in the book.
Finally, you'd get rid of kinetics.
So, you'd have what amounts to a first level Wiz who could have disable, dissipating touch, and sense link in their spellbook... and would be functionally identical to the psion... except they would cast spells rather than have supernatural abilities and therefore suffer from arcane spell failure chance..
The Wizard learns spells just as the psion does, save one significant difference.
A wizard's spellbook is idellibly etched with the spell written on its pages and the wizard MUST have the spellbook in his or her hand and reading it.
This means that each book is essentially a spell list the character has access to.
A first level wizard could have two spell books, and during down time could swap them out.
The first spell book might have Skate, Sense Link, and Synthesete, and the Wizards other spellbook would have Crystal Shard, Deja Vu and Demoralize.
As the wizard levels up he can add to these spellbooks whenever he has the opportunity to research a new spell or ability or naturally when he levels up. However, no single spellbook may have more than maximum number of spells the character could have at that level.
This means a level 5 character could have two or more spellbooks that had 11 spells (upto lvl 3 and following the psion spell progression), but would have to wait until 6th level in order to inscribe 2 more spells in each.
Due to the inherent paradox inscribed into the tomes a character may only carry a single Spellbook on their person at any given time lest the fields that surround them come together and begin disturbing the natural order of things (limbs and digits go missing and so forth).
This is why Wizards libraries are so "weird" and prone to having bizarre things in them.
Finally, change the name from Wizard to "Sage" and allow them to cast the psions healing power abilities as well. Allow body purification to be used for poisons, diseases and other miscellany, but it's a caster level check to overcome.
