Can't take credit for the play on words here, since It's a line from the episode. But the writer of Asylum of the Daleks actually took the wordplay from a comic called "Metamorphosis," where the Doctor is the one turning into a dalek. sort of.
It's a bit silly, especially with the whisk becoming the gun. But Effective enough, I think....
Added a bit of color to the eye, just because it would be hard to see the change otherwise.
