New Waterfront Amphitheater?

I have often wondered why the Waterfront Blues Festival doesn't float a big barge over to the park as a stage and use the natural contour of the land as a perfect amphitheater.  Apparently I am not alone, but instead of a barge, a group is proposing a complete makeover with a lot of concrete and a permanent stage.  Hmmm...keep the grass and maybe we have something.

But where will the dragon boats land?  This is the only water level shoreline downtown.
