Some friends and I ran a not-multiboxed Rogue 3v3 team up to ~1800, we hit a wall when people had enough resil & hp to not be insta-ganked anymore. Our gear was pretty bad, mostly T4-5 PvE stuff, we could have gone higher with full S3 I'm sure.
Not sure if 5v5 will be better or worse, you have more burst damage to kill someone, but more people to kill as well.
Also, multiboxing + melee seems to be a nightmare to me, but if you can handle it good luck ! (and post videos!)
I've gone through calculations, and 4 Sub. Rogues with S2 daggerss or higher and the build I linked should be capable of killing any cloth-wearer with up to 15k HP in under 2.5 seconds.

On average, 2 of the 3 Ambushes will crit, each maximumly-multiplied by MoS, Opp., Shadowstep, and Murder (10%, 20%, 20%, 2% respectively). This will be followed by 4 3-4 CB Eviscerates and 8 white attacks (2 from each Rogue), each of these also increased by MoS and Murder. We're only 2 seconds into the attack at this point. If he's still alive, 4 good ol' SS'es will finish him off, especially with Dirty Deeds increasing the damage once he's under 35%.

By the way, I'm making one of these for each of my Rogues... it works in stealth - http://www.wowhead.com/?item=24128
