Would anyone be interested in doing an alternate universe of Equestria full of OC's?

Story:
The three alicorns who controlled the elements of Equestria have disappeared. For a while life went on like nothing happened, then the world changed. Plants have started to die and animals have started to attack ponies. The weather have been sporadic, one moment sunny the next a blizzard ravishes the land. The oceans have been churning and the rivers have almost dried up. Earth Ponies, Unicorns, and Pegasi have to team up and find out what happened to the Alicorns.

Alicorns (NPC)
Alkira - controls the skys and weather
Dylana - controls the seas and rivers
Heartha - controls the land, plants, and animals
