I would not recommend it.
It could possibly fry the control module or the ballast on the base of the bulb. Both the controller and the bulb would need to be 55 watt too.
The BMW d1s ballast controllers are pretty fragile, there have been countless people buying buying aftermarket bulbs and frying the OEM hardware.
This is why you should replace your hardware with quality products and matching controllers.
