I think it would be awesome. One of my favorite scenes is from the end of a Piefight Girls video called 'Paris Possessed' where she gets hit with about 20 consecutive rapid-fire pies without being able to wipe anything away. Can't image what that would be like with 100!
Get some people to throw multiple pies. I remember Lenny did something from a Pievids named Miss America. I remember the winner getting 10 pies within a minute. Anyone remember that clip?
If it's Lane +100 pies, I'm down with that! Just make sure you mix them up! Make some real, some shaving cream, some different colors, some with crust, some without, etc! You may also want to avoid a straight barrage and give her time here and there to "clean up" just a little by wiping some off. You COULD even go so far as to collect the mess as she gets pied in a giant kiddie pool b/c I'm sure by the end, it would almost look like she's in a giant pie.
