Considering GM's connection
Considering GM's connection with LG as a battery supplier, a future hybrid Corvette would probably use a small battery pack like the Porsche and McLaren hybrid supercars, as opposed to the LaFerrari's KERS system. Even Ferrari's latest SF90 Stradale uses a 7.9kWh battery to drive it's 3 electric motors (one in the transmission, and two driving the front wheels). Plus GM hinted at a new battery technology due in their 2021 EV models that will cost only 30% as much as those used in the Bolt today.
