Nope, None of the cockpit windows open in any way.
The Smoke EVAC handle is a primitive method of trying to get rid of SOME smoke. Downside is, that it depressurises the aircraft.
I doubt it would ever clear enough or all of the smoke.
Fact remains, that this is one of the worst things to deal with on an aircraft, and it is all to easy to come up with possible sollutions in the comfort of your chair infront of the computer, but alltogether a very different story when you are effectively BLIND and have a noisy, uncomfortable oxygenmask strapped to your face, that adds to your stress levels and impedes communication and vision further.
