Suugestion: Re-use mount skins

[Plok.5873]

I'm a sorta fan of the [Hummingbird Skimmer Skin](https://wiki.guildwars2.com/wiki/Magnificent_Hummingbird_Skimmer_Skin), which would IMO make a great skyscale skin as well.

 

That led to the idea to 'recycle' flying mount skins that feature a complete transformation. I assume extending eg. the [shimmerwing skyscale](https://wiki.guildwars2.com/wiki/Shimmerwing_Skyscale_Skin) to work as a griffon could be done without too much effort.

 

I suggest offering owners of such a skin to 'unlock' the use for other mount types via the gem store for a reasonable price.

 

tl;dr: why not let unique flying mount skins work as other flyers types as well?
