I must be missing something because I don't see how using a Cross Tee at the top of the PVC pipes will provide any benefits over using a regular Tee. Now if you were to measure from the top of the PVC pipes to the Tees already installed and cut the PVC pipes in half you could install regular Tees on the end pieces and cross tees for pipes in between. That would allow you to connect the end pipes and the pipes in between. This would give you a top square and another layer of support below.
