Counterpoints:
[spoiler]Convert Spell to Power
Your training has included basic magical theory as well as the usual psionic training.
Replaces: You lose your 1st-level bonus feat.
Benefit: You add Spellcraft to your class skill list, which allows you to attempt to convert an arcane spell into a power you can add to your repertoire. You treat the spell as a discipline power for the basis of learning it, and you must first succeed on a Spellcraft check (DC 15 + the spell's level) and then a Psicraft check as per the normal rules of learning a discipline power (see page 154 of Complete Psionic).

Because the spells are now effectively psionic powers, they are no longer affected by metamagic feats. [/spoiler]
So you get all sorc/wizard spells, bard spells and probably domain spells...after that, you're basically hunting down wyrm wizards and anything you get from that is DM fiat and should be discounted.
The last line is important even with magic mantle, because isn't proper TO procedure that specific overrides general? Magic mantle is very general while the "no longer affected by metamagic feat" line is quite specific RAW. I.E. Magic and psionics may be handled the same effect-wise, but any spell converted to a power gets the "no metamagic, please" tag on it. You would need an equally specific line "psionic powers are now affected by metaamagic." to counteract it.
Just another interpretation. I'd be interested to see if there's a more reliable divine->arcane conversion than wyrm wizard, because as I said, unless you're partying with one, that heavily relies on DM fiat as they are NPCs.
