It is possible, actually it is a sure thing because with infinite universes there is a universe for quite literally everything, trees rule the world, everything is metallic, giant gas based jelly fish, and even brightly colored talking mildly technologically advanced ponies. Of course the chances of us finding it infinitely small aswell and vice versa. Even magic could exists since the magic in Equestria seems to be levitation based which could be done by controlled via electromagnetic waves from a mutation causing a horn with stronger magnetic forces in it, larger the more force causing the princesses being able to raise spacial objects at a distance.
