Implementing features from other expansions

Maybe I'm posting this in the wrong place, anyways...
Everyone has their favorite wow phase, be that Vanilla, TBC, WotLK, ect... This is for many reasons, the game itself (new areas, dungeons, raids, quests) and also some new features that come along, be that Dual Specs, LFG, BG finder, Summoning stones and other stuff.
I know nothing of programming and making the game actually work, but I thought, what if it we could to implement features from other expansions to Vanilla? Of course, some features would just break the whole reason for playing in Vanilla, but there are some that could potentially make the game more enjoyable in some aspects.
This is just an idea, maybe this isn't even possible or maybe most players would rather play as it once was back in retail. Anyway, what are some opinions on this subject?
Thanks for reading.
