The hard part would be getting to the top of either passes. Once on top, the trip to Cirque or Langley would be on easier terrain.
Can't answer whether you'd be turned around before making it to the top or not. That's on the conditions and your skill level.
Lone Pine Peak has beautiful views and a trail for most of the way. A sample of what you'd see. This is from 3/4 of the way up the very picturesque North Ridge. You won't see this from the trail, but you'll see it once on the summit.
