I see it like this:
Jounin Team:
Darui/Kakashi are the main long range support capable of using powerful ninjutsus to attack from a distance, though they are still very capable of fighting in close combat, being as versatile as they are, it would be better for them not to. Kakashi will also act as the brains for their operation.
Guy is the close-range powerhouse, boasting taijutsu skills that are almost unmatched in the NV and speed and strength that may be comparable to the raikage's when using gates and is capable of utilising the 8th gate to completely overwhelm them for a short time at the cost of his life
Kitsuchi has shown several powerful earth based ninjutsus and has shown some great taijutsu as well. He would act as support for any of the jounins, though his power is more effective when on the offensive, so he would start out in front like guy.
Last (and certainly not least as most people think) is
Hiashi, who is one of the most powerful taijutsu masters in the NV next to Guy and is capable of shutting down his opponents chakra network. He also boasts the strongest defense on the field, his rotation being the largest and strongest of any hyuugas to date, which will be useful against almost every attack except for jinton. His abilities will definitely be useful on the offensive to remove the ninjutsu capabilities of their opponents and to attack from a distance using powerful hakke kushous.
Team Kage:
A is the powerhouse on this team and will definitely be on the offensive using his speed and power to gain the better hand of the battle
Tsunade is the combat medic and will act as support healing the kages and possibly going on the offensive if necessary with her byakugou and her incredible strength.
Oonoki boasts the most destructive ninjutsu on the field, jinton, being able to demolish anyone and anything that is within its barrier range. He is also capable of using his weighted rock techniques to increase or decrease the weight of any member or object, himself included so that [t]he[y] can fly. Due to his old age and experience, he will likely be the brains of the team and attack from a distance with his powerful jinton.
Gaara will act as support, being able to use his sand to attack from a distance and to defend his comrades in battle. His auto-defense, being one of the most powerful in the manga, will prove useful when fighting up front against his opponents
Mei's incredible arsenal of elemental ninjutsu will put her as the main long-range support. Her boil and lava release will be handy on the battlefield to keep her opponents on their toes.
This sounds so epic that I would be willing to probably make a fanfiction of this, with the outcome being determined by a vote from you guys
