Using Legends in the Training Ground

Sorry but this is more of a recommendation than a question. So I was thinking about the new Legend Fuse and I'm not sure if I would enjoy him and was wishing for a mode to try out Legends. Then I thought "Why not be able to use Legends in the training Grounds even if you don't have the Legend."

So my idea was to let players try out legends while in the Training Grounds, this lets players try out characters without finally earning enough coins to get them to ultimately not like the character and waste their time! Of course they wouldn't be allowed to play the characters in the actual Battle Royal until they buy or save enough coins for the legend, but this is just to test out a characters move set before you possibly waste your time.
