Creative team comps... viable or otherwise

I've always thought it would be cool to play an match where everyone on a team picks their hero according to a certain aspect of their visual look or skill set

for example

invisible team: clinkz, riki, bounty hunter, and broodmother, weaver

sanic team: dark seer, clinkz, slardar, lycan, mirana

ultimate heal team: omni, dazzle, necrolyte, chen, juggernaut

minion team: furion, broodmother, lycan, enigma, beast master

bone team: pugna, shadow demon, skeleton king, doombringer, lich

a team consisting of a single dominant color, blue, purple, red.

It would be interesting to test some of these out and see how viable they are, also feel free to contribute your own wierd team comps
