While I think that 3-6" of foam outsulation over a wood-framed stud wall  
is going overboard and unnecessarily expensive , different stroke for  
different folks and all.

I don't think that I'd go the brick ties to wood furring strips route.  
(Rotting wood if not treated, rotting hardware (unless all $tainle$$  
$teel) if using treated wood .

I think that I'd investigate the possibility of setting up a system of  
something like those Tee-shaped steel fence posts either on the outside of  
the foam or embedded in the foam if necessary to which wire brick ties  
could be hooked .

It'd be a matter of devising a means to anchor the tops and bottoms of the  
posts  and doing some number crunching to see if the "posts" would need  
lateral support back to the wood framed wall (perhaps at mid-height) but  
it'd certainly involve few penetrations of the outsulation than a  
conventional brick tie system.

Perhaps the T-bars could also be utilised to deal with the persnickety  
problem of how to anchor the 6 inch foam outsulation to the wood studs as  
well without having to use screws that are so pricey that you think abpout  
getting a pimp to handle them.

I mention the T-bar shape only because I know that they are cheap like  
borscht and strong like bool.
But perhaps some other shape may prove to be better upon investigation.  
Those hat channel shapes that are used for road signage may be an option  
too ?

Or perhaps the brick veneer itself could be designed to be self-stiffening  
via geometry so that ties become redundant ?
