With no reference to 'angels' directly, but still not likely to have a good effect in a earth-vs-heaven setting, would be _Knockin' on Heaven's Door._ I prefer the Guns 'N' Roses version, on my mix CD right after 'I Used To Love Her (But I Had To Kill Her),' but any of them would do. Precisely WHAT it would do... My money would be on turning him into a Kawuro-like human size angel for the duration... or untill the force that's behind the angels (which the canon says is God Himself) decides to let him change back. Unfortunately, that's probably a bit too normal-SI-behavior to actually use on screen.
