And even a single-classed Warlock cannot swap Eldritch Blast for a higher-level attack power, but can swap other low-level powers. My counterpoint stands.
As I stated, it points to a basic concept. Just because Psionic classes don't follow the same basic structure of the earlier classes I don't think that means that it should be exploitable, to get around the basic premise of that concept.
If you used a power swap feat in order to acquire a power from the off class, then I say go nuts. Apply the primary class exchange and then retrain, and you're good to go. If you've only bought into the dabbler feat, to get the absolute basics of that other class, then to me that doesn't qualify.
I'd say that my point stands also
