They didn't redo all existing content either time.
WoW did a major focus shift from Wrath into Cataclysm because of the exact same problem with their healer design in Wrath (people were running 5 man Heroic dungeons with no Healers because Tanks were so OP), and they didn't redesign all prior content to match that paradigm, either.
Moreover, when FFXIV did the stat squish, they effectively retuned all existing content, and for unsync they added the Epic Echo.
It's not at all an unrealistic idea as it's already been done in various ways multiple times, both with and without changing prior encounters.
