Without getting into the much debated philosophy of restoration/display of preserved things and how restoration can often cause degradation to the original piece, consider that just preserving the data in the manner you suggest also requires preserving the original software if you ever want to view it. Which requires not just preserving that original software but also all the external hardware and software that original software relies on. Quite often that's a dead end as it requires preserving an activation/license server that the preservers don't have access to.
