Here's a problem though. If you put the piping way high, many spray patterns may end up hitting your roof or walls. Why not run the piping just above the height of the shrubs on the tables. That way you don't need pop ups or risers on each head, but the heads height is placed for the optimal spread.
Or you could go with misters from up high.
I want to be able to walk underneath the piping.
