Some people try. both the lugs, center hole and bolt circle (.05") are different. Some people do it. If it is just for show it may be OK. I would not do it and certainly not drive it in a sporting manner. Lugs are 14 MM instead of 12.5 mm also.

Tadge addressed this in one of the Ask Tadge questions:
Tadge answered:
Curious why the C8 requires 7/8" lug nuts and 140 ft. lbs. of tightening torque up from 13/16" and 100 ft. lbs. for the C7
Thanks for the question ZR1Bob. Our move to a mid-engine architecture shifted mass rearward so that the Corvette's weight distribution is 40F/60R. We take advantage of that traction with more torque multiplication through our new DCT for improved acceleration. The wheel stud size, pattern, and stud count is based on the needed wheel attachment clamp load to account for vehicle axle load, tire grip and other loads that the wheel-to-bearing joint must endure. These calculations drove us to the M14 wheel stud size for the rear axle. Many generations of Corvettes have used 5 studs on a 4.75 inch diameter bolt circle. It was a very standard pattern for the industry. For this generation we are moving to the metric standard of 5 x 120 mm. This change has nothing to do with the loads, in fact they are very similar patterns. So much so, that some people may try to use wheels designed for one pattern on a bearing with the other. That is very ill-advised. I'm glad this question has been asked because we need to let people know about the potential mismatch problem.
Although not needed for loads, we elected to use the same design on the front axle to keep a common lug nut, similar bearing design, and aesthetics.

With a 2,280 lbs payload capacity and 7,000+ gross vehicle weight, I think Tadge's explanation of wheel stud size and count based on axle load tells you why the Silverado has 6. The C8 has a GVW at about 1/2 of the Silverado and a payload capacity of less than 20% of the Silverado

I think it could be done but likely not worth it. Since the lugs are bigger the wheels could be redrilled on the new bolt circle, likely enough material there. But I believe the center mounting hole would also need to be machined out. Likely would require a real machinist and proper setup, not a garage job.
