Can be, but is only about gender, so only mares/fillies

here’s the story….
 
it been many years sens Princess Celestia and Princess Luna left the ream of Equestria  
to a world beyond now Equestria is in the hands of Princess Twilight Sparkle and  
the The Legendary Maidens of Harmony..
 
Applejack element Honesty…. the maiden of seasons
 
Rarity element Generosity…. the maiden of jewels
 
Fluttershy element Kindness …… the maiden of the forest
 
Rainbow Dash element Loyalty….. the maiden of the sky
 
Pinke Pie element Laughter….. the maiden of joy
 
and……
 
Princess Twilight Sparkle element Magic ……. the maiden of the stars
 
in a world of magic and science are  
one of the same and ponykind has made great strives in technology
 
the element of harmony is pass down to a new generation.
 
Sweety Bell — Charity (successor of Generosity)
 
Dinky whoovs –– Compassion (successor of Kindness )
 
Scootalo —– Devotion (successor of Loyalty)
 
Babs seed––Integrity (successor of Honesty)
 
Twist –– Optimism ( successor of Laughter )
 
Applbloom –– Leadership (successor of magic)

Oh I see! Make the new elements phase out a pegasus! That’s discrimination!

But Rumble is colt!

Twilight did not outlive her friends. ;D
 
Alt. comment: It was Equestria all along. (Too tired to expand upon this concept. :T )

You could’ve evened the species ratio out if your replaced Twist or Babs with Rumble.
