Wanted to give something different per role, in reality I play Jhin ADC/Mid/Jungle and Kench Support/Top. I guess more accurately they'd be my second picks if I can't have Jhin or Kench.

Surprisingly, this would actually be a pretty good team composition.
Udyr and Nasus could be both a beefy front-line and viable splitpushers while Lux, Varus and Lulu would be great for sieging (waveclear, poke, peel, catch and disengage).

Wow.. this comp sucks dick. Kog will fail cuz no protect the kog conducive champions (And kogs present state literally demands at least 3 dedicated kog protectors), an AD-psuedo tank jungle and toplaner that takes forever to be relevant. The midlane is an age-old lane that doesn't really work anymore.
On the other hand, the engage is retardedly strong. Sona ult ww ult and fidd ult are all amazing engagement tools, imagine a well placed sona ult + ww ult to catch any missed targets followed up on by a Fiddle ult and kog barrage. Nasus just kinda walks past all of them and zones away the squishy targets.
Otter Fire1 votesI can see this comp working. With Kog'Maw, if you Q someone you can make a tank squishy enough to kill with minimal effort also if you play it right you can use Kog'Maw to bait the enemy team into a Warwick ult, Sona ult, Fiddlesticks Ult, you name it. Also, Kog'Maw's ult helps to execute if Fiddlesticks, Nasus or Warwick fails to kill on the first attempt. Overall, a pretty fun comp to play as. I would like to think mine's weirder than what you have.

This can actually work pretty well.
Kled and Noc can both build a bit on the tanky side and be divers, Vel'koz and join can stay in the backline to unload their damage and thresh can stop anybody who try to get to the backline, or he can make picks for his team.
