In that case, it'd likely be more reasonable to get a vehicle to the observatory, boost it back to Earth orbit, and then attempt to return it to L2 after on orbit servicing. I don't know what that Delta-v budget looks like, although I'm happy to throw coffee money someone's way if they want to do the math in this thread.
