Superstar recycle

As the game has moved further and further forward, new characters, 4star. 5star. New events, new tours... I have been taking a good hard look at my roster... it has dawned on me that not only is there dozens of superstars in there that I don’t use, but also most of them I have never used... in my 2-3 years in this game there are characters that I received early on that are still my bottom talent, I have never had call to use or advance them...this had lead me to think that as everyone’s roster is bulking into hundreds of superstars, would it not be a great idea to introduce a feature where by you could recycle unwanted characters for tp and tokens of their class, or even coins.
