Because of all the rock in there, do I still have enough area for sand
to create an good DSB? Should I start over or just add another 2" of
new sand to what is already there?

Adding new sand to already setup tank is tricky...
Water will be mess for couple days and it could smother corals.
When I built my DSB the water was milky white for almost a week.
