I tested that out... but I wouldn't recommend it:
-The second screen basically gets disabled. All windows from the second screen get moved to the first. The switching takes long.
I'm not sure if its possible in unity, but I can rightclick the border of a window and select "No Border" in KDE.
This window then completly behaves like a fullscreen - it gets full focus (your mouse can't escape it), it seems to leave the rest of the desktop alone, you have to alt-tab to get out, it is just notably quicker versus having actual fullscreen.
