Here's a list for using some of the Advanced Powers in the Mongoose Traveller Psion book only using the 5 Basic Talents. That way, you can still use the Psions you rolled up with the Core Rulebook - instead of having to roll a brand new one. One dot "." in front of the power means it's from the Core Book, Two dots ".." means it's from the Psion book Advanced Powers section. To use, just replace the Advanced Talent in the task listing with the Basic Talent I now have it listed under.
Example:
Read Aura
Aura Perception, Psionic Strength, 10-60 seconds, Easy (+4).

change to:
Telepathy, Psionic Strength, 10-60 seconds, Easy (+4).
Costs 1.
