I really, really, really want to see Midna come back, but I don't want them to do it at the expense of the story or for TP's ending to lose meaning.

Because that's exactly what happened when Sonic Adventure 2 fans (me) were handed Sonic Heroes. And Shadow, The Game. And Sonic 06.

Anyways, I think it would be interesting to see the possibilities of a TP sequel. Based on that translation quote, things may have gotten worse for Hyrule - degraded technology, anarchy, tribalism, magic becomes prevalent. But also based on that quote, the Hero of Light himself may not make an appearance, more like a descendent.
