Getting to instances are really easy with RAF summon a friend.... that mage is still on RAF so he can start a chain of summoning, so yeah, I will try SFK then

Using DK is not possible because:
1. this main account has a DK on another faction already
2. I do have a 78 DK with good tanking gear from UP/HoS etc, but he's on the same account as one of the toons I want to boost

dam it I didn't plan this thoroughly lol
