Go for it, that's what I've done.
I have a 2-hole stand thankfully but I'd like to make up a full set (or two actually!).
A Chap Mark Ellis on other forums has managed to measure-up a genuine 3-hole stand and has made drawings available for it (I'll try to find the link), but I'd love original examples of single and 3-hole stands myself for display purposes.
An angle iron frame is fine in the meantime
Have you any photos of your gear? I'm all for No.1 related photos
