As I am sure you are well aware, electrons are consentrations of localized energy, not hard little balls, just as quarks are, and QCD is a quantum theory of quarks. The quantization of these "forces" has to do with making particles (quanta) out of the force carriers, and we call these force carrying particles bosons. So, basically, we are talking about energy interacting with energy.
IMHO... Just as we needed to first understand what matter and energy was before we could quantize it, then develope a theory(s) (E.g., QED, QCD), we need to first understand what spacetime really is before we can develope a successful theory of quantum gravity.
