Well, first of all, you need a neutrino in there as well, otherwise the
spins won't add up.
But we do know better than we did in 1933. The deep inelastic scattering
experiments done in 1968 at SLAC show three points of deflection, with
fractional charges. There were no leptons (electrons or positrons) in
evidence -- those have integral charge.
