Shoes for Plastic Pipe

>Gents:

Can anyone suggest a method of supporting PVC pipe in a rack designed for steel pipe?

We are installing a pipe rack to support several 4" and 6" steel lines, uninsulated. One end of the rack will support two 4" PVC pipes. We originally designed the pipe so that all invert elevations were the same, but we forgot that we would have 3-1/2" shoes on the steel pipe.

Would you suggest: 1) lowering the invert elevation of the PVC pipe to rest directly on the pipe rack? or 2) fabricate some sort of shoe for the PVC pipe?

Thank you for your help.
