I believe that in Sanji's case, it is definitively tied to his world. Technically it could be possible here, but practically I don't think it would.

That said, I understand what you mean. I suppose that there's nothing in here that could further help with your dream back home with it being so specific and clear. Unless the whole land of Equestria was brought here, which, I expect isn't possible at all.

[It's one thing to bring people and ponies from different worlds, almost one by one. But bringing a whole land with all its people? That would be too much.]
