This sounds reasonable to me. Antechamber actually computes a minimized
structure when computing am1-bcc charges, but it doesn't save it anywhere.
But you could run the same mopac geometry optimization yourself. Of course,
how accurate you need the geometry to be will help determine whether
semiempirical QM is good enough, or whether you need a more accurate
calculation.
