I'd take:

Lux - She's always positive and she has the powers to light up any that might come up, she can help other champions to never give up and she also provides lots of power in case they need to fight.

Zilean - He can control time and rewind bad stuff that has happened. Being able to warp through time can also help get through sticky situations and in case of unavoidable death he has Chronoshift.

Ezreal - As many have mentioned, Ezreal's skills as an explorer will surely come in very useful at most tasks. Also he tends to be friendly so he shouldn't be in a conflict with a fellow member.

Fiora - In case the team needs to fight strong foes Fiora the Grand Duelist will be ready to take on any fighter that dares challenge her. She seems to be very strong in combat and a very reliable duelist to take on anyone who tries to stop them.

Wukong - He seeks to be the best, he is a very calm but very strong warrior. He will be in the enemy faces leaving nothing but dust at the end.

So how I see this is Lux and Zilean provide the team with support (moral and other), Ezreal provides leadership, Fiora and Wukong provide the team with fighting skills. Now the possible arguments I see are Fiora and Ezreal, I don't know why but I think Fiora would want to be the leader, not allowing Ezreal to be one :/
