You could also use the 4E engine to clone 3.5 or Basic. Sure you would strip stuff out and rewrite monsters but you could do it.
Sure, where i'm going is that I think it would be hard to imagine a 3.5e fan disliking 3.5e just because it was presented with a 4e paint job or a 5e fan disliking 5e just because it was presented with a 4e paint job. They may not like that presentation quite as much but their like isn't going to turn into outright dislike of the game.
Which is what I find absurd about the position that it's just 4e's presentation that made so many dislike it.
