You may be able to pull the whole bracket off, I know it slides forward enough to do an intake gasket job but not sure if there's anything keeping it from being completely removed beyond that point.
Disconnect the throttle cables and fold the a/c compressor over to the passenger side, disconnecting the refrigerant hoses at the plastic bracket near the alternator first so you don't kink them.
But you'd still probably have to cut the pulley apart to take the pump out of the bracket. At least you'd have more room then or just grab a bracket from a salvage yard.
Worth a shot maybe, otherwise cutting the pulley or maybe using a torch would be in order.
