I have 3 existing accounts, all with tons of level 70's and 60's on them. I would like to try 5 boxing and have been trying to figure out the best way to do it via RAF which will allow me the ability to level them all quickly.

The only possibility I see is if I use 2 of my existing account to link to 2 new ones, and link one new one to an even newer one, then pay to have characters from the third old account moved to one of the new accounts and then cancel the third old account. The third old account is really a level 70 and 60 and the rest are small mules and stuff.

Is there any better way?

Also, it would seem to be better to me to boost using my level 70 shammy on one of my main accounts, in instances (grouped with 4 others), then use granted levels at 60 to create my 5th on the main account.... make sense?
