Yes, I would just sit tight. Do you know how large those Echinodorus plants will probably grow? The E. bleherae in my 115g is up to the surface. While they often regularly sprout new leaves, they go through growth spurts, usually once or twice a year I find. And you may have inflorescences too, with daughter plants.
Thaks for your comments on my tanks; to return the compliment, but certainly being sincere in doing so, your aquascape is looking very nice. The pygmy chain sword, once it gets going, will cover the substrate within a couple months.
