Lvl. 40 heroes change up!!

Hello clasher's, its Clancy again with another idea i researched and saw nothing else like this! I noticed when you upgrade your heroes to lvl. 40 or max level they only change statistics or appearance only changes a little! I'm excited and i want there to be more a point to get max heroes like a colour change or something. I understand if a update with hero appearance wont come out since maybe in the future TH 11 will have new hero levels and then there will be a visible change? i just overall think players should feel more appreciated to get max heroes since it is so vary hard!!!
Thx and keep CLASHING!!!!
