Warmoth can cut a seven-string pocket in a lot of other bodies (for a fee, natch) but I would guess that might not be one of them - unless you wouldn't mind the sides of the neck hanging over the edges. The neck plate & screw placement is the same, the 25" scale length is do-able (maybe have to move a pickup route?), but the neck would overhang the body by 7/32" on each side. Looking at the pictures, it probably wouldn't even look bad, if you can talk/bribe them into doing it. The highest-fret screws on the seven neck look closer to the body than on a Strat pocket, otherwise you could just but a V body and re-shape the pocket yourself.
