Triple support in 6v6?

I really enjoy 6v6 and have been wondering what metas might develop and would love to hear thoughts on what comps may become meta.

If 2 tank 1 DPS 3 supports became meta, would it remain Brig Zen Lucio or would one of the newer supports take ones place? Might we end up seeing more Juno Brig Zen rush comps or Bap Brig Zen with Sigma Orissa?

As for the 1 DPS, my first thought is Mei who kind of has the utility and sustain to function as a squishy tank already. I peaked GM2 on open queue but am washed in diamond right now, whatdya think 6v6 meta comps might look like?
