Well, if you're not looking for TFA specifically, there's a couple very nice, LONG fic series. Ouroboros by bedlamsbard is Padmé/Obi-Wan/Anakin and 456k words. Re-Entry + Re-Entry: Journey of the Whills are together well over a million words and counting; the primary ship is Qui-Gon/Obi-Wan, but there's a LOT of other ships, mostly untagged.
