Need RaF planning advice

So I currently have 3 very old accounts with a few sets of tri-box toons. I'm toying around with the idea of adding two more accounts

Account A -- Has 80 DK available for boosting
Account B -- Nothing of note
Account C -- Nothing of note

My plan is to add Accounts D & E. My first plan was this...
Account B recruits Account D
Account C recruits Account E

I thought that I could then create a new 5-box group, level them until about 8 or 10 as a group, then switch toons on Account A so that my DK could instance boost Accounts B thru E. Then use level grants on Accounts D & E to catch up the new toon on Account A. But I think I read on Blizzard's RaF FAQ that the level grants can only be given to the linked veteran account (E grants only to C, D grants only to B).

So, can the Recruit accounts grant levels to a non-linked account? And if not, anyone have suggestions on how to work this around?

Close! You cannot grant to the non-linked account. The linked accounts can grant each others toons. So Boost b-e to 60, then second team to 30 and grant those 4 to 60. There might be more grants but I am not sure about those. But I did grant 1 RAF from 10-60 using 3 of my toons.

So... Is my only real option to boost an additional group(s) to 60 on the RaF-linked accounts, and transfer a toon to the main account?
