It was a WoD only moment. The only way to play the old models is to play classic.
WoW also didn't upgrade/update its engine with WoD. It literally just made new character meshes, textures and rigs.

Dawntrail updates the entire way shaders are handled and objects and characters respond to lighting (which is also higher quality), and how shadows are cast in turn. Asking for an option to choose the old characters is like saying "just give us the option to flip a switch on a fundamental engine-level alteration."
