I'm betting you could make it to Trail Camp with the microspikes. There might be a few places you would wish for bigger spikes -- just above Lone Pine Lake, if the trail is covered by snow. If you can follow the trail, then that area would be ok. Climbing above Mirror Lake, if the snow coverage is good, people leave the trail and head up the slope directly to Trail Camp. In that area, the trail hugs the slope on the right, so it could have some steep sids that you would be better avoiding.
