Is there a way that an erudite (Complete Psionic 153-6) with the expanded class option convert spell to power (The Mind's Eye Web column "Expanded Classes, Part Four: Ardent, Divine Mind, Lurk, and Erudite") can manifest as a power a 9th-level or higher spell?
Such an erudite, according to the article, "treat[s] the spell as a discipline power for the basis of learning it," but the typical erudite "can learn a discipline-only power only if it is up to 1 level lower than the highest level power he can manifest" (CP 154). So even if "each time [an erudite] achieves a new level, he unlocks the knowledge of two new powers of any level or levels that he can manifest (according to his new level) from the psion/wilder power list" (CP 154), he can still only convert to powers spells of 8th-level or less.
Is there a psionic version of the epic feat Improved Spell Capacity? (The epic feat Improved Manifestation does not actually let an erudite manifest 10th-level powers.) Can such an erudite take the feat Epic Expanded Knowledge and select a spell that's converted to a power?
How can this be done?
