Homebrew SteppIR Moxon

I came up with an idea that, to me at least, seemed interesting. Imagine a
Moxon design, a sort of "double D" "[]" arrangement. Imagine this
arrangement encased in a PVC square or rectangle.
Now, picture standard copperwire making up the elements and attached to
each distal end is fishing line leading across the [] to the other side.
This is true for both elements.
Now, imagine a take up spool and motor such that the length of each
element can be adjusted in SteppIR-like fashion. With the proper
electronics, it seems you have a Moxon with adjustable resonance...a sort
of homebrew SteppIR. I would imagine that the useable bandwidth would not
be as great and at the appropriate length, the Moxon becomes a two element
Yagi.
Any comments? From the "big guns"? "Duff-Man"? Anyone?
Thanks!

The most critical elements of the Moxon are the tail lengths and gap
spacing- change that and you lose the F/B and the natural 50 Ohm feed.

Thanks for the replies. Back to the imaginary drawing board.
