If the court is made of something other than concrete forget it. Asphalt is out for sure and I don't know if a clay court would hold together.
When you tip up the end slab, you will have a 2ft x 4ft area of bare soil. With the next planters end tipped up, you now have a 4ft x 4ft bare area. Maybe the compost bins go there.
