So in the wee hours of 12 last night, I sketched the Mane 8 as how they will look during the main squeeze that is AiM, finalizing their designs and ages.
Twilight. 47. Doesn't look older because Alicorn. Probably a little bit taller.
Starlight. 52. Is supposed to give off an old teacher-esque aesthetic, not sure if I'll keep her hairstyle. Might give her reading glasses.
Rarity. 50. Really looks her age, and wears different head/tail wigs because her illness caused hair loss. Though her favorite is the blonde one AJ made for her. Usually has flowers in it that Pomme and Lovesong would bring to her.
Applejack. 49. Super stocky. Keeps hair short.
Pinkie Pie. 48. Hair longer/fuller, and inherited a Rainbow Power gradient over time.
Fluttershy. 49. Keeps bangs shorter and mane in a braid. A little taller/lanky.
Rainbow Dash. 46. Youngest of the Mane 8. After Turtledove is born she gets a pixie cut, shortest of the Mane 8 but not by much. Can still punch you into next week.
Sunset. 53. Oldest Mane 8. Pulls hair back in a ponytail.
there u go. Flurry Heart is 25 current AiM time, so subtract 25 from them to see my ideas of their canon ages
