Writing a story

So I have about 5 note pages on chapters I could write for a story I was thinking about. Basically the beginning starts in the future (of ponies) where our protagonist is on her fathers ship (transport vessel). Stuff happens, protagonist doesn't hear abandon ship and goes with the ship into an anomaly (probably a black hole) and crashes onto equestria about 10 years befor nightmare moon (so in the future she can move to ponyville to meat main six). She gets adopted, goes to school, yadda yadda. There will be a skip after the first day of school to graduation at Canterlot school for gifted unicorns (a year or less before Nightmare moon) since nothing of interest would happen then

This is th first 4ish chapters so I was wondering what you think about this idea. (The future is based on Elite dangerous type of future)
