I can't really see a need for either of them. CV3 and SOTN still look fantastic and play even better. It's not like say, DuckTales which was imitating a TV show you could get closer to with modern graphics and sound. You could remake SOTN and CV3 sure, and they might even be good remakes, but I doubt they would be able to capture the spirit or all of the fun of the originals. And I say this as someone who didn't play either until about 5 or 6 years ago.
