Unless champion has insane catching mechanics, there is no point in jungling with very weak or no CC. I wouldn't ever put Katarina and Akali into jungle. Fizz has really hard to apply CC before 6, but as well - catching mechanics. Teemo also has no point except good counterjungling. Zed was played in jungle before, but due to niche CC and damage nerf, he just wasn't too effective and his popularity went into midlane.

Cassiopeia is very situational and can still lots of kills not on purpose. She also needs good items to snowball well, which isn't the point of jungling.

Darius, Annie, Ryze can work here, but are really dependant on clear ganks (removing wards before) due to their lacks of mobility. Though, i've played few rankeds as Darius in jungle and i agree, he is absolutely legit and if used well can be insanely good.

Kayle, Singed, Blitzcrank, Jayce, Pantheon and Poppy have insanely good ganking mechanics, with exception for Poppy - not insanely good, though still noticable - and are enough tanky to gank quite oftenly, so the fact that they're unseen in jungle is either better effects on other position or increased skillcap.

While Taric can jungle well, he is just better support, so people don't really want to do it. However, tried him twice and i must say, he is really safe option for hard games.

Morgana is my love in jungle. Though, it's unbelievable how hard is she countered by gapclosers, making her simply unable to gank some champions.

Talon also should be here more often. Dunno why people don't trust him.

Karthus is situational too. I don't think his clear time would be too high, isn't it? Though, Wall of Pain and the allmighty Requiem from random moment... Seems funny, but not really viable. Also hardly countered by Flash or gapclosers.

We can put likely 3/4 of all champions into jungle. Even if i'll remove Katarina, Akali and Teemo from your list, then i can still add such champions as Leona, Renekton and few others.
