Simply put: I'm running a Warlock who multiclassed into Psion. The feat that makes him a multiclassed Psion grants a 1st level power. Eventually, this PC will be taking the Dreamwalker Paragon Path (Psion). At 13th and other levels, you are "encouraged" to swap out powers of lower levels with powers of the appropriate level.
For single classed PCs, this process is a no brainer. Likewise for hybrids. For a multiclass PC, however, they have a power sitting there that either is or is not swappable at 13th or higher.
Its perfectly clear he cannot swap a warlock power for a Psion power without a power swap feat. That isn't what I'm asking about.
I'm asking whether that 1st level Psion power gained via the feat can be swapped for a higher level Psion power at 13th level (or whichever would be the appropriate level for that power).
