I currently have my boxing config setup to completely fill both monitors, with no borders or space between the instances of wow. So I have to Alt-ESC to get back to my desktop when running everything. I'd like to setup it up where each window runs in a standard Wow windowed mode - title bars, taskbar shows, etc.

Can I just flip the border style in ISBoxer to "Application defined" on all 5 windows? Will it cause any odd behavior? Will I lose the instant swap and scaling?
