When you say "work around", do you mean leg room?
Should be a straight forward build. Rectangular or right angle triangle (RAT will allow for leg room) framed from 2X4's and a piece of 1/2" plywood (cut to outside dimentions) screwed to the side. A rectangle would be easier, as you could just size it to just side in and use wood wedges to compress it (ie carpet, etc). A right angle triangle. Would need to be solidly bolted to a wall.
Remember, the brace only needs to be as wide as the tank (maybe a bit less) and I think most 55's are 15" front to back.
