That works too. Tethered already shows that simply looking at things works perfectly as well, no need to point with your right hand. You can also have a transparent menu show up next to where you click to shorten the travel time between places to point.
I would suggest to use a normal controller. (After an hour holding up and pointing motion controllers all around will become tiring) Freely move the viewpoint around with the analog sticks. Use you gaze as a pointer, with face buttons doing different things depending on what you're looking at. They could pup up different transparent menus when you look at a spot on the map or have simple commands assigned after you select a group of units.
