If you're willing to do the Anderson to Gunsight shortcut, consider going off trail from Smith's Fork Pass to Anderson Pass.
If you're comfortable with off trail travel and reading a map, I highly recommend this. Once you get down from Smith's Fork
stay high and follow the most direct route until you hit the trail going up the south side of Anderson. All above tree line,
good views from the top of Yellowstone, save dropping down and coming back up and shorter.
Here are a few of my images through that stretch:
