Papers submitted to the 34th International Cosmic Ray Conference (ICRC 2015, The Hague) by the IceCube-Gen2 Collaboration. IceTop is the 1 km2 surface array of the IceCube Neutrino Observatory. Measurements of ground level particles by IceTop have been used for high resolution measurements of the cosmic ray spectrum for energies of 2-500 PeV. Composition has been studied by considering coincident measurements of TeV muon bundles in the 2 km deep IceCube neutrino detector. Including IceTop data for GeV muons may reduce uncertainties inherent to hadronic interaction models; however, all three parts of this program are somewhat limited by the size of IceTop. We explore the potential for IceCube-Gen2 with surface components (IceTop-2, "veto") to improve the cosmic ray science program. The increased area would permit a factor of ∼ 3 increase in energy range for the spectral measurement, a factor of 50 increase in coincident data, and enable lateral and production depth muon measurements for every event.
