There is another form of confinement that will be a bit of a problem.
Wikipedia says; "Owing to a phenomenon known as color confinement, quarks are never found in isolation; they can be found only within hadrons, ..."
Also; Electrons are smaller than quarks. However, quarks vary in size. A single electron is about 1/5th the size of a very small quark. So all electrons are smaller than all quarks.
