We consider the collisions of the SN ejecta with these massive CSM shells as potential cosmic-ray (CR) accelerators. If ~10% of the SN energy goes into CRs, multi-TeV neutrinos and/or GeV-TeV gamma rays almost simultaneous with the optical/infrared light curves are detectable for SNe at <20-30 Mpc. A new type of coordinated multi-messenger search for such transients of duration ~1 - 10 months is required; these may give important clues to the physical origin of such SNe and to CR acceleration mechanisms.
