10 box raf help with some existing accounts

[Osud]

So i want to start 10 boxing ele shamans and need some help with raf

is there anyway that i can achieve the following while still getting xp benefit in dungeons

What i have
Note: all accounts that are green are on one bnet account, red is another bnet account
Account 1: 85 shaman -account already exists
Account 2: 85 shaman -account already exists
Account 3: 85 shaman -account already exists
Account 4: 85 shaman -account already exists
Account 5: 64 shaman -account already exists
Account 6: no shaman -account already exists
Account 7: no shaman -account needs to be created
Account 8: no shaman -account needs to be created
Account 9: no shaman -account needs to be created
Account 10: no shaman -account needs to be created

I'm thinking of running account 7-10 throught dungeons with a level 85 hunter i have on account 6

I was wondering if theres a way to link up raf so that i can get a lvl 80 shaman on accounts 5 & 6 at roughly the same time?

or would it be easiest to just lvl the 64 shaman to 85 seperately and do raf from account 6 as if im starting to 5 box from scratch

5 > 7 > 9
