Hmmm.. very difficult to choose. It really comes down to sticking to themes but keeping to roles, just like in a normal game.

First of all you'd need at least 2 physical DPSs. So other than the banned dudes maybe Varus and Wukong. I've also seen a lot of success with Ashe and Nocturne. You'd generally need at least a melee and a ranged.

A sustain support would be useful, Sona fits almost all themes except tanky, she has both an AD and an AP build, can heal for quite a lot and poke for a lot of damage. If you do have a tanky line though and want to engage then Nami does what Sona does, except she can do it pre 6, She doesn't have as much damage as Sona though.

Next there'd be a magic DPS, while Xerath is the obvious choice for a poke comp I think that it's actually because you forgot about him while planning the banned champions so I won't include him... Brand is an amazing dude on ARAM, he has a counter tank passive, long ranged poke, a stun and an AoE ult which can be quite devistating to a grouped up enemy team.

The last one is a little fuzzy and comes down to what you actually want. So far this is lacking in hard engage so a Leona can jump in and lock up a target to be assassinated, she has actually quite a lot of damage herself too. Another hard engage is Galio who's AoE ult along with Wukong, Sona and Brand's can demolish an enemy team outright. You may not want hard engage though, in which case you can go for hard DISSengage and pick up Janna. Extra special mention goes to Soraka, who is a closer ranged AP carry/Healler who unlike Brand can build a rushed Abyssal Scepter without sacrificing damage, Soraka whien built tanky can even validate a penta AP comp because her MR shred gets utterly ludicrous.

So yes I'd say my perfect all mid teamcomp would be:

,, , and

With Varus, Sona and Brand there's some crazy poke coming out at the enemy team. Then Leona can dive in and assassinate someone, her passive has some amazing synergy with Brand's passive too.
