Ahri, because I love gumihos. Additionally, she is capable of fighting against any creature, due to her attacks being capable of being both 'physical' (in the 'your body is ripped to shreds' aspect) and 'mental' (see Fox-Fire lore).

Sona, because she can provide moral support to the entire team with her music, as well as actually empowering them directly; or ripping anything that can hear her a new one.

Lee Sin, because he won't get distracted by anything and is all kinds of cool. He's able to use echolocation, so he's not going to be prone to being ambushed-- thus making a very effective vanguard. And um, if this were a match, I'd need Physical Damage dealers.

Ezreal, because he's an explorer, so is probably able to map well so we don't miss anything. He's got an eye for treasures, so certainly he'd find something that the rest of the party might miss. He can easily serve as a scout and rogue, so he's good to have in any party.

I think to finish this off.. Skarner (or Shen, Nautilus, Nasus, or Malphite) would be appropriate. Somebody who is known for their durability and concussive blows, if you will, to create space between them, enemies they're fighting, and the rest of the team. I think Skarner fits that best.

Alternatively, replace Lee Sin and the tank to favor ridiculous range-- two of Lux, Jayce, Xerath, or Kog'Maw.

As a team dynamic, I wanted people that would not disagree much. Ahri and Lee Sin are both Ionian to an extent, Ezreal does as he pleases (including invading Noxus on expeditions), nobody wants to mess with Skarner, and Sona is just so nice that it'd be hard to get angry at her, and she wouldn't get angry at others. /opinion

Heck, that may even work as an in-game team.
