Mounting the headlight in that area puts the lamp in peril, making it likely to get broken in a fall or when the bike is parked by a rack and gets knocked by other bikes. Typical fork mounts are further feeble. I am aware of one good mount only, Zinkens Dynashoe - benefits of the design should be apparent in the photo:
Not too worried, since I'm also planning to mount a front rack soon to accommodate batteries and controller for a front hub motor. Once everything is built out, it should do a fair job of shielding a Magicshine clone or similar there.
