Or is it made where that can't be done?

Yea,there's one tab and two "raised areas" at 4 and 8 o'clock respectively. Isn't the biggest problem the fact that H4s are dual filament and H7s are single? The plug I posted will go from a H4 plug to a H7 bulb. He could always buy a H7 plug and wire it in or retro fit a H4 bulb.
