Well, folks have enjoyed the Wetsuit Fluttershy 01 and Action Celestia from my Deep Six dream concept so how about some Rarity.
When the Royal Sisters and the other members of Deep Six need a pony who is knowledgeable about the inner workings of high society they turn to Rarity. The young fashion designer has the pose, looks, wits, and knowledge to mingle with the upper crust of Equestrian society, but she is of low enough social standing that she’s able to move amongst the elite almost unnoticed when she wants to. Her vast network of connections throughout the fashion industry and high society gives her a direct line to gossip and scandal that roil throughout the world of Equestria’s wealthy where so much intrigue occurs.
Rarity is not a combat master like Rainbow Dash or Applejack, but in close quarters combat she is still quite deadly with her special double-ended rapier designed to be used exclusively with levitation. Also she has a trusty ally in Spike who is always by her side in battle.
