[3.5] Solo Cooperative Metamagic

[tuesdayscoming]

I'm looking for a way to apply the Incantatrix's Cooperative Metamagic ability to a spell that you yourself cast. Note that it need not be precisely the same entity who casts the spell and who applies the ability: for instance, the Wu Jen's Body Outside Body spell still requires two 'bodies', but is accomplishable by, effectively, just the one Incantatrix.

Any other known shenanigans?

Apply it to a planar bound Trumpet Archon or Ghaele. Some cleric buffs are really nice. Bonus points if you Psychic Reform one of his feets to occular spell.

Dvati with the Trickery Devotion... then add lesser planar binding + mirror mephit for simulacrum SLA 1/day.

Using the psychic power Schism should do it, though getting access to that might take a hefty bite out of your casting build.

Leadership? Not solo, but can be pulled off by a single player.

Hmm, hadn't considered Trickery Devotion, but that just might be the perfect solution. Simple and elegant (provided it would actually work; I need to check on that). Any particular reason it would need to be a Dvati, though?

How exactly would the Trumpet Archon/Ghaele work out? Sorry, Im AFB.

Schism would also be a great solution, bur alas the particular build Im working on already has every single level dedicated to something completely necessary. No room, Im afraid.
