repositioning for the new era

I was thinking about comps that could play off of Azir's isolation abilities and wanted to get a little feedback about comps. Granted Azir only has the wall ability for isolation and disrupt of fights. What would work best off not only this ability but his stun as well, especially considering you can multi stun if done correctly, making him that much more valuable for a comp. We already know Lee sin's ability to knock an opponent into the team and this can work very well if a wall was place(not sure if a kick would be treated like a terrain knock back therefore being able to kick though the wall). With Azir being mid or supp there is 2 roles filled both with the ability to isolate at least one target each. Trist might be just as valuable jump, knock,peel, then jump. So there would be a third position. Either mid or supp could then be filled with Thresh or Oriana, both able to not only mass disrupt and peel(not Thresh of course, that where team comes into play) but also isolate a target. So that 4 roles filled, I'm have a had time figuring whether the top should also play off the potenial(like Gragas or Malphite) or it just be a filler for needed tank or dmg. You get a tanky character on Thresh so not sure what would work best. I'm open to suggestions of course for roles to be filled, but the team fight would just not even be a thing if done right(you could even be behind and tear it up). Thanks for you time.
