I actually love the idea! I wanted to do this at my daughters baby shower, but she couldnt wait to tell friends/family that its a girl! I have been to one of these showers and the hosts were so creative. Really a lot of fun! They revealed the babies gender by wrapping a giant box with a large ribbon that was filled with blue helium balloons. When the bow was untied, the balloons escaped into the air. They got great pictures. Of course, since no one knew if it was a boy or a girl, gifts were all neutral. I guess this can either be a pro (can be used for later babies without worrying about color) or a con (no cute clothes just for a boy/girl).
