The answer is no because even WOTC didn't attempt a watered down DS.Absolutely.
There is a version of Dark Sun that can be salvaged. It's going to look like the 4e version at minimum and undergo the same level of revision as 5e Ravenloft. The question is: is there enough of a market for this Nu Dark Sun amongst players who weren't fans of the OS DS, because you're going to lose them to the purity test.
Some settings, genre/style combos, and worlds just aren't money makers as "fully compatible with 1st party content" content without an IP propping it up.
