The Ponyville confidential one could actually be an interesting setup for something, But the Mare Do Well idea is, quite frankly, rather tiresome when you consider the mane six never did anything THAT bad. I mean, they were no saints and there was probably an better way of handling the situation than they did, but they didn't even actively mislead Dash. Everything bad that happened to Dash was her own damn fault.
Mare Do Well is something that really shouldn't have a big overblown event directly afterwards, but I can see it negatively effecting their relationship in the long-term, and implies some not so nice feelings and opinions that could be explored, just not in anyway that I think your standard fan fic author is capable of.
I could have gotten the whole thing wrong, but has anyone ever considered the past version of Twilight is in a time paradox? If she spends the entire week trying to prevent a disaster only for her future self to warn her of said disaster, then then how did Twilight learn where the time travel spell was? Her future self told her, and her past learned this from her future self, but she never actually learned it to begin with.

Ask The Mane Six
Paradoks would be if Twilight in end could change past or didn't go back in time at all.
And what we got it was standerd Stable Loop. Not fan of those but It's not something what ruined my enjoyment (and i love that episdoe).

It's actually one of my absolute favourite episodes.
Unity of the Sun Mare
Yay, then I am making sense! I's a winner.
But for the record, I do quite enjoy the episode. Second to the Cutie Mark Chronicles as my favorite episode of the series.

"It's About Time" is one of my favorite episodes, too. Best Pony and time travel in the same episode? Very yes.
