MSD 250/2 in Roboscan 218?

I recently purchased two Martin Roboscan 218 Pro II Units and after doing some research online, I was curious as to what the possible challenges would be to putting an MSD 250/2 in there instead of the MSD 200 Lamps in them now. The Roboscan 218 and 518 have the same ballast on light parts.com, and from what I read they have the same starter for the lamp as well... It seems as if they could handle it with a better fan to push more air through and cool down the lights more. Anybody have any input on this?

My opinion, FWIW, is that if you are using a ballast that has a calibrated output for a MSD 200 then just swapping the lamp may not get you anything brighter.
