Not without damaging the wing and maybe the trunk lid--there is not much room in which to work but maybe you could get in there with a Dremel tool and a small cutoff wheel to cut the bolt? Or maybe cut and split the nut.
It is mostly likely that the bolts are turning in the plastic pillar, leaving the only option to pry the wing off, ripping the stud heads from the pillar. And then deal with the damage afterwards (mount a couple of studs with JB-Weld, etc.).
