Legendary Chroma for Dragon Trainer Tristana - 4 new dragons

As 4 new dragons got announced some time ago and already roam freely on the PBE. Those guys will surely produce some offspring too and as Riggle is seemingly a hatchling of the Base Dragon species (which seemingly got turned in the Fire Dragon), why shouldn't there be also a Riggle for Water, Earth, Wind and the Elder Species?

I propose a chroma for Tristanas legendary skin 'Dragon Trainer', which only changes the model of her dragon Riggle to fit with the new dragons. This will surely be a bit more expensive than the average Chroma, but I bet many followers of the Riggle-mania would buy it.
