Is this possible in a mod?

Hi, take a look at screen shot and see where arrow is pointing.

I want to take the data that is available when you right click on an enemy (when in combat) that shows it's health and place it on the alt display while in combat as seen in this mock up screen shot. Consider it just that I want that information displayed but don't care to have to right click on every enemy before I attack each and every time that I wish to find out what their health stat is, which seems to be the way that I play the game almost every single time.

Is this possible and if so what would be the procedure to do so?
