I’m liking this idea.  
I would think this would explain where the HUMAN Sunset Shimmer has been, but it would also mean that EqG is canon, and that would have been a glorious amount of tears to drink.

I expected Trixie.

Pfffffhahahahaha! XD

Gonna post this again just cause my mind is too blown think of anything else:
 

@Background Pony #5693
 
“I murdered your mother Twilight.”

Part of me wishes this were true since it would mean Sunny-sun finally gets her much-deserved appearance in the show. But, I’m also well aware that doing so would completely nullify the development of one of my very favourite characters.
 
On a completely different note: HI SUPEREDIT! It’s been a while since we’ve seen your brand of awesomeness.

@Kibate  

I just now imagine if it had been real, the livestream-chats would have exploded

starlight is human sunset shimmer as pony at equestria

Hory sheet it’s SuperEdit!

I like Starlight Rimmer better

This makes me feel better about accidentally calling her Starlight Shimmer… several times.

Aw sheet!
 
@Mori  
Heh, puns.

“It’s me, Twilight! It was me all along, Twilight!”

THE HYPE IS REAL!

And I’m sure if we dig deeper we’ll eventually reach the conclusion that the Illuminati is somehow involved

That would have been a twist…

Gasp!  
That ass is gorgeous!

Oh my god! This would have been the greatest plot twist.

And this is why memes endure: Creative possibilities despite the many failed attempts.

Mind blown!
