Should MLP have aliens?

If Starswirl can discover different worlds to banish monsters like the Sirens to, what if there are other worlds that are capable of sending something to Equestria?

They don't have to come from outer space (even though I think it'd be cool to see). But with aliens, the animators are free to design them however they want, without the restrictions of following existing mythology for all the other creatures in MLP's universe. They wouldn't feel out of place as long as they look cute enough for kids.

Case in point:

  Reveal hidden contents

Plus, it creates room for even more friendship lessons for later seasons. No one in Equestria's population would know what to expect from something that came from another world. The ponies, griffons, yaks, dragons, and changelings would all perceive said aliens in different ways. So rather than repeating the same morals regarding prejudice, this could delve into something more political. Like how different points of view can create an unwanted, and often destructive, divide in society. Obstacles to friendship don't get much bigger than that.

I don't know about aliens. Too much explanation is required about Equestria space to take away the mystery of the moon and how the sun works.
