Agreed- in fact, I have long since homebrewed three out of four of those.Having a Psion class is a good call.
I agree with [MENTION=12731]CapnZapp[/MENTION] that a lot of past psionic archetypes could easily be ported to subclasses of preexisting classes:
* Psychic Warrior: Fighter Subclass
* Soul Knife: Monk or Rogue Subclass
* Wilder: Sorcerer Subclass
* Ardent: Bard or Cleric Subclass
