For a 16 day trip I suggest focusing on either a northern loop or a southern loop, not combining sites far north and south. For a northern loop, which it seems you might prefer since you have a personal connection to the area, consider adding Jasper, Columbia Icefield, Banff, Grand Teton, and various places in ID, OR, and WA states. If you do it in September you should be reasonably okay in terms of weather.
If you can't go until later, that would be a good argument to do a southern loop instead. Conditions in Grand Canyon, Zion, Bryce, Capitol Reef, Escalante, Arches, and Canyonlands are great in October.
