That's just a generic flat shroud, it's not a good design. Air will "pile up" on the flat sections of that shroud, it's not really efficient. You can get a generic flat shroud fan set up like that on the cheapest radiators out there, I'm surprised Griffen gave it that little thought. And the spacing and location of the fans doesn't maximize their coverage. Do you know the CFM output for them?
A dual 1.25" tube core shouldn't be much different in width than the 3 core Champion I run. It has .75" tubes, but 3, and obviously there's space in between the extra row. I would bet the cores are probably within a 1/4" of each other.
I would ditch the fan set up before I did anything else. The Ford Contour set up I run would fit that 26" radiator. The shroud is angled toward the fans (hard to tell in the picture, but it is), the fans are not just bolted to the back of the shroud itself, and the fans are offset. The fan motors are pretty deep, but they're offset from most of the major components. Your serpentine set up is a bit more complicated though, so they may still interfere. The fan and shroud combo is pretty cheap though, $135. Heck you might even be able to return it if it doesn't fit as long as your careful with it...

My full install is here, but you can see what I mean from the pictures...My "new" '74 Duster- or why I need a project like a hole in the head
