You can make the region darker but it requires you to edit the XML file, and I believe it needs to be done each time you load up a character set. I'm sure it's on Lax's to do list however there is currently an alternate method of approach.
Just setup Healbot on all of your characters. When positioning it use mouse repeater so everything is identical [assuming you have all your windows set to the same resolution]. You can see in zanthor's video, that Ualaa linked, that by checking the Block local click (KVM Mode) option the click is not passed to the current window and only to the healer's window. This way you can see exactly where you're clicking on each window without having to use a darker overlay.
