I was also thinking Charlotte Dome as I was reading your post till you mentioned 6 pitches. Charlotte Dome is 12 and 5.8. Maybe a little more involved than you're looking for.
The Tuolumne suggestions are good but may not yield the true wilderness experience you're looking for (I'll probably get flamed for that comment).
Matterhorn Peak's North Arete is also an option.
Humphreys East Ridge.
Lone Pine Peak's North Ridge or North East Ridge.
If you're willing to do the hike, Swiss Arete on Sill is 5.8, not too long and not too much 5.8.
