it COULD be possible, but as we all know
Good things arent so often made into equally good things in live action.
cough cough, Avatar, DragonBallz .. it all depends on the execution of ti all
If .. say it was done kinda like the smurfs .. a portal into the human world type of thing, following the standard movie formula of
Hero/heroine(s) meets twi and the gang
team realises they need hero/heroines(s) help in some way
they do some good
something bad happens (main guy/gal loses hope)
sad montage etc.
twi still trying to save the world, failing miserably
some form of flashback/realisation for main char(s) and faith restored
TO THE RESCUE
KIckass fight scene and explosions and rainbows etc.
after fight speech by Hero/Heroine(s) thanking ponies for being there and all that other mushy stuff
everyone says bye and goes back to whence they came (bad guy in tow if he was imprisoned, if not the magical item that gave him power with them)
hero/heroines(s) life now better than before, have picture keepsake of them and the ponygang on a desk to remind them
Happy ending YAAAY .. confetti and parties

Possibility of sequel hinted at, depending on reception of film
it could be a good movie, depending on the writing and all that. i'd definitley go watch it
heck if i had the money i'd direct it so no hollywoodian could butcherize it
