When I made my D&G scopes I found it difficult to source light weight metal tubing. So I made the tubes from thin ply. That has worked out very well however I would consider rebuilding them if decent metal tube was available at reasonable expense.
Your hexagonal ply tube, even at a seven foot length, would probably be stiffer than a thin walled steel or aluminium tube and they would require wide spaced tube rings and bars to support them. I always wondered how people baffle and paint the inside of those long metal tubes. Laying up a ply tube, at least the way you did it, seems very sensible. The test would be to check the collimation sag on the mount.
