That's a very peculiar take on the "any ability" description of manipulate form that many people seem to have, yet I will never understand. Just because it says "any ability" it doesn't mean you can just make them up. That would be like selecting the feat "I can never die" when creating a character, then presenting it to the DM that "it never says I have to select a feat published in a specific source" as to why it would work.
I know pun-pun is an excercize in the absurd. But if you don't stick to the rules there's no point in even the exercize.
