Triple monitors: Would 2 x 1680x1050 side screens work ok with a 1920x1080 main?

Hi all,

My main screen is a 27" widescreen with an actual vertical screen height of 13.6", I'm after 2 more monitors with the same screen height, but I can't afford 2 more 27" widescreens just now so I figured 2 (4:3) ratio 22" in screens have the same vertical screen height, according to the cool screen size calculator here: http://screen-size.info/

But all I can find at the moment are two (16:10) ratio screens that do 1680x1050, not quite the 1080 HD res my main one does.

Are...
