That would be nice, but the fans would be enraged unless..time travel in future where we see her as aged and taller keeper of castle and school?

Anyway  Glim Glam represents IMHO the future Alicorn, with Celestia the alicorn of past and legends, Twilight the alicorn of present and able to create a special link with 5 other ponies.

Celestia chose  to uplift  Cadenza mi Amore to alicorn status for important deed and  she  was destined to handle and rule the long forgotten Crystal Empire cursed by evil Sombra, while Twilight was selected to handle the elements of Harmony that after Luna ' s rebellion were  useless to be wielded by Celestia alone and to free Luna from the curse of Nightmare Moon.....for Starlight Glimmer, she was 'discovered' by  Tree of Harmony, forced to escape from her dystopic town for a fluke thx to  Fluttershy and the ponies of Our Town, she went on planning revenge on Twilight through time travel and  she surrendered (note not defeated, because no physical or magic action coud stop her from destroying Star Swirl spell and end the time loop) to the pony  that ruined her twisted dream of equality through  an heartful speech, not a moral lesson like before or some taste the rainbow moment.

Choosing her as pupil (without consulting Celestia, instead of Sunset Shimmer if we consider EQG canon) it has been her first role as teacher/mentor like Celestia, sure she got headaches and  some disappointement when  Starlight brainwashed her friends or acted with her guts with Luna and Celestia, but her trust in her pupil allowed to crush  Queen Chrysalis ' s domain, gaining a new ally (Thorax and reformed changelings) and also saving the elements of Harmony  during Shadow pony 's confrontation. Even in Season 08 Starlight managed to support and help her mentor during a time of Doubt about the school of friendhsip (and screw the EEA rules) and that's why outside Celestia, Spike and her brother is the closest friend and near sister, even closer IMHO than the Mane 5, because both accomplished magicians, link as mentor and  atoner pupil and they help  each other  especially about school problems

That's why IMHO Starlight will become an Alicorn, because she is the pupil  and achieved great deeds for her mentor and alicorn princess Twilight, like Celestia did  previously for Twilight too
