Alternative to standard Model A stone guard

[waxhead]

I am not overly keen on the look of the standard stone guard that can be bought. I am chasing ideas on how to make a different style stone guard. Ideally I just want one that fills the hole in the radiator shell, rather than cover the entire shell as the standard stone guard does.

Feel free to post any ideas, including how to mount or fix the guard in place.Pictures also appreciated. Thanks in advance.
