Yes, you can. Steve (MBenz) once explained to a member how it can be done. I think it powers off of the dome light wire. But the only think is that the dimming would not operate in reverse or something like that (Whatever it was, it wasn't relevant or really needed anyway).
However, I am unaware of how this would physically fit in place of the old one.
