These actually are off the same base, I don't know if they could 100% be restored, but look at the back of each ghost figure, look closely and you'll see the outline of both Scooby and Shaggy. Look at the backs of most of these props and if they were reused for a different SD:HC prop, a lot of them are still labeled with the original name on the back. Look at the back of Potion Group #7 (Lot #79) and you'll see it's labeled "money bag 1". The shape of the cutout resembles the money bags from the bank scene in the same area.
