Nope.
Off the top of my head - the Avatar is a monstrous creature, so he can't join units. He can be joined by the farseer, but then the wraithguard get left out.
So one way or another you'll need those two fortunes, and since the Avatar is already taking up one HQ slot, the other one must be Eldrad.
So this has to be another variation on the Avatar/Eldrad tag team of doom.
Depending on the league, you'll find that this combo will get docked a lot of comp score because some players tend to find it cheesy. (i.e. competitive).
Although having said that, probably the only way not to get docked comp scores against these players is by losing, so play like you've got a pair and take what you like.
