Aye! I love this question Well the show would now revolve around Rainbow Dash's archetype. Similar characters I could think of are Korra of Legend of Korra, Violet from Arcane, I'm sure yall could think of others. So thinking of how Rainbow Dash is I'd point out a few elements about her: cocky, loyal, fun loving, afraid to show affection at times, secretly afraid of underperforming that she covers up with boasting. Twilight was a smart pony who did not care about having friends (except Spike). She valued research and academics, and the show (at first) revolved around her learning how to be a good friend and evolved to using those lessons to assist others with problems and more nuanced situations as the show went on. So in the later seasons newer writers fell short of writing good RD episodes or good supporting Rainbow Dash. For every good episode there was one where she was a total "B****" I assume this was because of the lack of direction. They probably described her archetype but forgot to mention how much growth she's had and then you have episodes like "2,4,6, greaaat" which are terrible and make her look terrible and not like a good friend. For this show to work it would have to be her learning how to be a good friend and really embody her loyalty element. Possibly involving her joining the wonderbolts. Maybe having the rainboom becoming one of her special abilities to defeat enemies instead of just being for show. Etc. etc. etc. I'll paint a quick picture: Rainbow Dash is shown being a mean pony to somepony meek "(let's say Fluttershy cuz of already established lore). And possibly other scenes where she's being just generally selfish and mean possibly on the sports team at her school etc. similar to Twilight being in magic school. Her antics end up having her expelled. Her parents want to put her in a better environment to improve her behavior. So they move to Ponyville. Fast forward multiple years and she is an adult but not much has changed with her personality. She still has the cloud busting job. She meets Twilight Sparkle who is studying abroad on a mission from Princess Celestia, tho this time she isn't as disinterested in friendship so the focus could stay on Rainbow. Twilight meets Rainbow and at first Rainbow doesn't like some pony over her shoulder critiquing her work but is interested in Twilight being involved with the princess and being from canterlot. Not too much at first. Remember Twilight was at first a bit full of herself during magic school and a bit after cuz she thought she was smarter than everyone etc. so in this version she will be almost matching Rainbow's boastful nature and they start having friendly competition. Rainbow is enjoying this which is new to her. Quick somber scene where she sees Fluttershy walking in the village and Rainbow is pondering but we dont know what. Nothing happens. She had plans to meetup with Twilight and right when they're about meet BAM! Nightmare Moon. Twilight was distracted hanging out with Rainbow she never looked for signs. And bang they work together to find a way to stop her leading into a friendship between the two. Their able to weaken her together with the magic of friendship they gather together but will need to find clues to defeating her the next time they encounter her. In this version I envisioned Nightmare Moon being a constant villain throughout the season as opposed to being finished in the two episodes. Also she is weaker therefore not making her a constant threat and still allowing for a slice of life feel of the show. Rainbow encounters the rest of the main six throughout the season and slowly gains a relationship with them along with others (scootaloo etc.) She already knew them after living in Ponyville for years but after getting a relationship with Twilight she has a new outlook open to friendship etc. They will be working together to discover the secrets of the elements of harmony. Twilight gets her element in the first two episodes with Rainbow's help, the rest of the mane six get theirs throughout the season and Rainbow finally gets hers "loyalty" at the end of the season and theyre able to stop Nightmare Moon in the end. Maybe a little bit too serious. But this is one way where I think Rainbow Dash being the main character would work and be enjoyable imo. (late night writing am-I-right lol)
