It is done all of the time and I have never heard of the sides blowing out. Usually the gap that is filled with silicone is 1/16-1/8 on each side. You also have the bowing effect in the center of the piece. Personally, I like glass so I have never used acrylic. Also I think poly-carbonate absorbs less than acrylic, I know it is stronger.
