Concerning future lepton-nucleus colliders, International Linear Collider (ILC) and Plasma Wake Field Accelerator-Linear Collider (PWFA-LC) electrons in order of 0.5 TeV and 5 TeV, respectively, colliding with Super proton-proton Collider (SppC)'s 3075 TeV lead ions, are considered as "linac-ring eA" options. In addition, 1.5 TeV option of the Muon Collider (MC) vs 3075 TeV lead ions of the SppC is also taken into account as a "ring-ring muA" collider. Luminosity values of the SppC-based eA and muA colliders are estimated. 3075 TeV lead parameters for 100 km-circumference option of the SppC are taken into account to optimize luminosities of electron-nucleus and muon-nucleus collisions, keeping beam-beam effects and disruption in mind. It is shown that luminosities of order of 10^30 cm^-2s^-1 can be achieved by moderate upgrades of lepton and nucleus beam parameters.
