Are there any top laners who are ACTUALLY good junglers? I've seen Riven, Darius, Tahm (if you count him as a top laner), Cho, Aatrox, Irelia, Gangplank, Fiora, Garen, Gnar, Jayce, Mao, Olaf, Nasus, Renekton, Rumble, Ryze, Shen, Sion, Singed, and Wukong.
Are any of these good?
You're also missing Naut and J4 (who were both originally top laners before being in the jungle.
I have a blast playing 
You are forgetting someone...

used to be very good before everybody got a dash, now it's incredibly hard to land a good Q except in chaotic teamfights and in the very early game (you know, that stage where Q depletes your mana very fast).
Lee Sin, Rengar, Rumble, Wukong, Olaf, Mundo can fill both roles reasonably well.
Shen, Aatrox, Maokai, Fiora, Riven can do both but aren't great in the jungle imo.
I'm sure there are other champions I'm missing. Elise isn't bad top either.
