What's your ultimate idea of a MLP Crossover?

I have an idea for 'somewhat' of a crossover..

I find it would be funny to see them all meet their pony.mov selves.. Even just the excuse to use the characters of Pony.mov would be awesome.. I could use a lot of 'my' humor, for the characteristic, partically Spike (witch is why I Liebe him even Mehr the Fluttershed, witch is a LOT to say)..

Homestuck
Pinkie Pie - Feferi
Twilight - Eridan oder Sollux
Fluttershy - Tavros oder Aradia
Rarity- Kanaya
applejack - No idea Terezi oder Equius maybe
regenbogen dash - Vriska oder Gamzee

Team Fortress 2, Adventure Time

Batman
X-Men
star, sterne Trek

Homestuck

Metroid
Regular Zeigen oder Hawaii Five-0

um....Black ★ Rock Shooter? oder K-on....hmmm....Series of Unfortunate Events...Narnia.....nah,i got nothin'

I might get flamed if I say this, but I will anyways...

Snow White and the 7 Dwarfs.

Ice Age
*please don't judge me*

MARVEL SUOERHEROS!!!! It would be soooo cool!!! (But it has to be marvel!

Doctor Who, Teen Titans, Powerpuff Girls, Dexter's Laboratory, Justice League, Legend of Zelda, Gender swaps of ALL the ponys, Spiderman, Sonic X characters, and the Harry Potter characters. There might be more, but these are the only ones I can think of right now. I know, one heck of a crossover. I am doing this in my spare time right now, and thinking of making a fanfic of it.

My Little pony and Mario Kart, called "Pony Kart". The image I brought in is an example of regenbogen Dash in her kart. I didn't draw this, because I will draw my own pictures of the mane six in their own kart.
