Here, we study the processes e + e - → K$$0\atop{S}$$ K$$0\atop{L}$$ π 0 γ , K $$0\atop{S}$$ K$$0\atop{L}$$ η γ , and K$$0\atop{S}$$ K$$0\atop{L}$$ π 0 π 0 γ , where the photon is radiated from the initial state, providing cross section measurements for the hadronic final states over a continuum of center-of-mass energies. The results are based on 469 fb-1 of data collected at or near the Υ ( 4 S ) resonance with the BABAR detector at SLAC. We present the first measurements of the e+ e- → K$$0\atop{S}$$ K$$0\atop{L}$$ π 0 , K$$0\atop{S}$$ K$$0\atop{L}$$ η , and K$$0\atop{S}$$ K$$0\atop{L}$$ π 0π0 cross sections up to a center-of-mass energy of 4 GeV and study their intermediate resonance structures. We observe J / ψ decays to all of these final states for the first time, present measurements of their J / ψ branching fractions, and search for ψ (2S) decays.
