How about Dvati as the race?
They don't ever work as a team, so it doesn't fit.
To the point, here is what I've come up with. I hope you're alright with hyperconscious.
[spoiler]
--Satori--
Elan Telepath 6
1-Linked Power
1B-Psicrystal Affinity
3-Metapower (Mind Thrust, Linked Power)
5ACF-Telepathic Communication
6-Mindsight
Powers (ML 6):
1- Psionic Charm, Detect Psionics, Sense Link, Stone Mind, Mind Thrust
2- Brain Lock, Read Thoughts, Recall Agony, Inflict Pain
3- False Sensory Input, Hostile Empathic Transfer, Mindful Aura, Solicit Psicrystal
Notes: Satori is used to following multiple trains of thought in other peoples' heads, so she plays the action economy with linked power and solicit psicrystal (reflavor the psicrystal as her third eye). Recall Agony fits the bill for her "flashback" spellcards.
--Koishi--
Human Wilder 2/Aberrant Paragon
Dragon 332 3/Wilder 1
1-Willing Deformity
1H-Deformity (madness)
EE3-Darkstalker
6-Enervation Endurance
Powers (ML 5):
1- Psionic Sleep, Attraction
2- Ego Whip
Notes: Immunity to mind-affecting effects (but pays for it with -4 wisdom) from level one, hide and diplomacy as class skills (with regards to maximum ranks, anyway) and a more subtle ability set. +2 to charisma and constitution from Aberrant Paragon.
