I can't comment on how well it might work, but I like your train of thought. The only thing I might add is rather than taping them together use heat shrink tubing. If the real hot rods aren't assembled using heat shrink tubing they use something very similar. You can get heat shrink tubing from any electronics supply house such as Mouser or Newark.

. If you don't have a heat gun to shrink the tubing you can carefully heat the tubing over your stove.
