Well the DM is tweaking some themes anyway... Lemme copy and paste some of the house rules.
Themes: Pick a Dark Sun theme. Noble Adept does not give you 1 free power point. Escaped Slave does not give you free Bluff training.
Adept's Insight, Noble Adept Feature
With mental focus, you enhance the undeniability of your attacks.
Encounter ✦ Psionic
Free Action, Personal
Trigger: You miss with an attack roll during your turn.
Effect: You add 1 to the triggering attack roll. If the attack still misses, you do not expend this power, and you cannot use this power until the start of your next turn.
Augment 1: Effect: You instead add 1d4 to the triggering attack roll. If the attack still misses, you do not expend this power or the power point, and you cannot use this power until the start of your next turn.
New Power: A character with the Dune Trader theme can take Psionic Formation in place of Quick Formation.
Psionic Formation, Dune Trader Feature
You weave phrenic energy into a brilliant lattice that surrounds a foe and sears it of life and vital fluids, withering the enemy as you allow your allies to move into a defensible position.
