Mounts *Spoilers Included pre 30*

So we all know that we can mount on a chocobo and on a unicorn and so on. My question is will Square Enix be implementing a feature in which instead of using a chocobo to fight I could say use my unicorn, personally that option would be a low priority update but the idea I feel should be expressed because I know im not alone.

and the magitek armor fighting would be really awesome

Or my Couerl.

I'd also like to be able to use the barding I buy for my chocobo on my Couerl (or the weirdly skinny unicorn if I make a Thaumaturge) or my Magitek armour.
