Help for a Player Who Only Plays Bruisers

I primarily play Singed top, though I am going to branch out a bit more after the next patch, learn some champions named not Singed, but I need to figure out some things I can do in other lanes.

Currently I know how to play Shyvana, Shaco, and I am learning Lee Sin for jungle, I could use someone bulkier too, suggestions?

I need a bruiser I can play instead of an AD Carry out of bot lane, this one has me stumped. I plan to pick up the new Murderkaiser for this reason, but I could use an alternative, for when I can't play Singed top.

For support I am comfortable with Taric, Leona, Singed (of course), and Pantheon (I'm actually more comfortable with Panth support than Panth top).

My mid laners consist of Singed right now. Anything bulky (other than Cho, I do not enjoy playing Cho) champs I could take mid?

What do I like about Singed?

Mostly annoying people while being bulky enough they can't simply blow me up if I'm not going in 1v5, as well as being able to ensure the death of high priority targets by flinging them into my team.
