You can get a call changed from incomplete to complete, but any further action wouldn't be allowed (if the receiver had subsequently gained yardage, for example, the spot would still be at the point of reception, assuming the whistle blew).
Wow............ thanks.
It's this type of situation that argues for abandoning replay and just letting the refs call the game. The ref clearly blew the call, but he also blew his whistle. There's no way to make it right.
