If the Grides were just a tad too short but otherwise OK, why don't you go to a good bootfitter and have them punch them out a bit? They're not extremely stiff, but you could have that same bootfitter soften the flex if you really need it. Did you bake the liner? Put a thick pad in the front while baking and you can probably squeeze some extra room out of them.
Remember, ski boots are supposed to be a bit tight. Size the shell first. Take the liner out, and stick your foot in the shell. With your toes at the front of the boot, you want about half an inch of space behind your heel. My toes hit the front of my Denalis if the buckles aren't cinched down. They fit as close to perfect as I can imagine. AT boots aren't hiking shoes, they will not be fun to walk downhill in.
Oh, and if you like the Garmonts, get Megarides. Then you can use Fritschis at the resort and Dynafits in the backcountry. :)
