Nope. Not a good idea. You are still falling from a pretty good height and people break arms when they trip and try to "catch" themselves all the time. It's best to just topple over on a bicycle, hang on to the bars and try to let the hard bits of the bike hit the ground first whether you are moving or standing still.
