Dream team? Sounds more like the FREEM TEAM!
No, but in all seriousness, 8 of ANY ranged/support toon is epic. I could see an AR/NRG superteam being crazy, but I imagine it would only really open up once you got Flamethrower—Buckshot and M30 aren't really enough AoE damage to make heads turn. I almost think AR/Dev would be more powerful, since you could create huge Caltrops/Ignite fields and plant trip mines around the edge to blow them back in if they started to run.
I have seen the 8 Elec/NRG super team run personally.
it was absolutely ridiculous. Did you know that eight powerboosted ball lightnings is enough to drain a purple boss?
When something good happens to me, I can never enjoy it....
I am always too busy looking for the inevitable punchline...
BEHOLD THE POWER OF CHEESE!
I still want to be in an 8 Mercs MM team... why settle for eight guns blazing away at the enemy when you can have 56 of them? 
Cascade, level 50 Blaster (NRG/NRG since before it was cool)
Mechmeister, level 50 Bots / Traps MM
FAR too many non-50 alts to name

2 is enough for anything but AVs. My wife and I have a pair of AR/nrg/ice. range boosted snow storms on the bosses means that nothing gets close enough to hit you.
A pair of FA with BU and Assaults means that only the bosses survive your alpha. By the time you finish them off with burst and slug, FA is recharged and ready to go again.

I have an AR/Elec that I love to play, only ranged boosted with enhancements. I would totally be down to get on an AR superteam if anyone else is interested.
8 Blasters. All Range Boosted Assault Rifle. Full Auto.
Nothing could ever survive the opening salvo to make it in range. If anyone has ever tried to superteam this, or has experimented in some way similar...
Please, share the experience so I can live the thrill vicariously.
