Maybe you can consider a shrimp goby with a pistol shrimp. The shrimp will move alot more sand then the goby could ever do. You could also add like 10 nassarius snails to help out. The sand sifters ability to sift the sand is rather weak compared to the ability that other marine friends have. Plus the symbiosis between the shrimp and goby is really quite awsome.
If you do really want a sand sifting goby I personally like the engineer goby.
