Splice thru the feed to the outdoor box, put smart switches at outside box, put a one button on/off controller at entrance to room. The one button controller just needs 110, and your switches at the door will now have power. You end up with one spare at the front door from the entrance box.
As far as toggle style stuff. I have seen x-10 switches that fit the toggle opening, just the are push buttons, not toggles. Not a big user of x-10 so some one else may have more input.
