SAS, there is only one size of windows on all 225s used for oil and gas, its not an option. IIRC in the very early days (2005) EC decided to make the enlarged windows standard. I suspect that the military EC725 and maybe some early VIP config aircraft don't have them, but then they have different types of door and are not designed to spend their lives over water.
Lets see, finding a tiny window in a huge cabin vs finding a huge window in a tiny cabin - which would be easier?. Not sure, though not finding oneself under water is obviously the preferred option.
