It would probably form no beam at all. The bulb HAS to be at the focal
point (center) of the lens.

From what I have seen on the web, the so-called "HID" (which are just
filamented halogen-type bulbs with xenon instead of iodide gas) are
designed for boy-racer types wanting blue lights.

True HID lights don't have filaments, which is why they are also
called gas-discharge lights... the gas itself is what gives off light,
not a hot glowing tungsten element. This is also why they don't come
in little boxes... they need really high voltages and current to work.
