This is a good idea. I too have an outlet right at the back of my tank and ran an extension cord through my stand and mounted a powerbar underneath my stand to plug everything into.

if we go with a 2" bulkhead for the emergency then the overflow box width will be 6" from the back of the tank , so if your tank is 30" the overall width is now 36" , as far as spacing goes from the wall as long as your tank is level then 1/2" -1" is more than enough, you need only enough space so that the box doesnt touch when the tank settles.

if we go with 1 1/2" drains then the box can be 5" and 4" for a 1" or 3/4" bulkhead.

we dont do smaller than 4" as it becomes impossible to work in.


hth
