You're getting lost in the sauce. What you're describing is a Freaky Friday situation.

>Scootaloo wakes one Friday and is in Rainbow Dash's body
>the night before, she had a fight with Dashie about how Dashie was ignoring her
>today is Scoots' birthday, and she just woke up as her hero!
>at first she's elated to fly around the Cloudominium and get to take care of Tank
>then Spitfire and Soarin show up and berate her for being late for flight practice
>Scootaloo, with no training, repeatedly crashes and injures herself trying to perform maneuvers
>she gets Dashie suspended for being a flight hazard and is kicked off the Academy grounds
>moping, Scootaloo goes to the clubhouse to relax, and finds Applebloom and Sweetie
>her friends ask her, not knowing she's Scoots, if she's seen Scootaloo
>Scoots finds out "Scootaloo" (Dashie) hasn't been seen all day
>Scootaloo puts the pieces together and realizes Dashie must be in her body
>has a panic attack because Dashie not only can't fly, but also found out Scoots is homeless
>Scoots tries to keep acting as she thinks Dashie would in the hunt for "Scootaloo"
>AB and Sweebs quickly put 2+2 together, but think finding Dashie is more important
>along the way, Scootaloo keeps witnessing more of Dashie's life through her eyes
>finds out from background ponies how much Dashie does to try and make Scoots' life better
>market stall ponies who set food aside for Scoots did so because Dashie paid for it
>fillies who went to the CMCs did so because Dashie put in a good word for them
>any time her scooter was repaired, Dashie paid in secret so repairponies could pay their rent
>Scoots struggles being the Element of Loyalty when the Mane 6 ask for help on an adventure
>doesn't succeed in helping a pony who injures their leg because she's not fast enough
>loses track of Tank
>at Scoots' lowest point, she sees Applebloom and Sweebs run off with a gorgeous pegasus filly
>Scoots finally gives up and starts crying
>after letting it all out, Applebloom, Sweebs, "Scootaloo", Tank, and Twilight approach her
>Dashie, as Scootaloo, explains that she asked Twilight to help her out with a body swap
>Dashie had been thinking a long time about how to make Scoots' birthday special
>but, when Dashie got to the Cloudominium, Scoots was gone (because of the Wonderbolts)
>every time Dashie would catch up, Scoots would bumble off, wasting precious birthday time
>eventually Dashie realized she would never be as fast as Scoots
>got AB's and Sweebs' help, decided to enjoy a spa day, using Scoots' body as cover to relax
>Scoots, in Dashie's body, sees herself for the first time, and she's drop-dead gorgeous
>Dashie asks Twilight to cast the spell again tomorrow so Scoots can have a good present
>Scoots, realizing how special she is and how much she's cared for, refuses
>"But why not, squirt? Someone's gotta show you how to fly!"
>"I don't need to fly, Rainbow Dash... I've already got so many friends that help me soar every day!"
