Go for it. The further your eye is from the source of the light at night, the better your brain can interprete what it sees.
Hmmm.....maybe if I had a brain.
Anyway I got a Cateye Volt300. Works for me on my commute. Mounted on handle bars. I dont think it could fit on any part of the forks tho.

) but back in the late 70s I had a bike with a light on the front fork that was attached by bolts and a sharp screw that dug into the fork. At ~20mph the light bracket decided to work its way loose and swung into the wheel.
. Alternatively you might be able to bolt an existing mount on to it, subject to you finding one that will accept the bolt. Clip on lights are not ideal for fork mounting for this very reason.
