While it's certainly possible to use the plastic frames with wood stringers you kinda miss the advantages of both methods doing it that way. Doing it all wood (ply frames and wood stringers) means the stringers can be easily glued to the frames, nothing glues easily to UHMW. Also the ply frames are quite a bit lighter than the plastic ones. The plastic frames allow a fairly easy snap fit to round aluminum tubing, would be tricky to do that with square section wood stringers.

You're only looking at one piece of plywood, the frames are really pretty little.
