You can try it but you have to be pretty lucky. Everything came together for Sedin on that one. If the goalie sees it is a ridiculously easy play. Even if the goalie is screened there's a good chance it will just hit. All that being said, that was an awesome goal.
The NHL is at 5/8"s now but I don't know about USA hockey. The one test I know works is putting the stick face down on the floor and trying to slip a AA battery underneath. AA batteries are exactly 1/2 inch.
