Combining ascended characters

With the current champions 2.0 we're able to increase characters 'til 550. That's a long run even if we're talking 4*. Winning ascended for the same character is very painful moment for advanced ppls as mostly unable to use for anything. Example is having 2 ascended 4* and winning a third or having 1 which is already ascended to 5* and winning a 4*. This issue can be solved elegantly giving an option to increase ascended lvl's by adding duplicates.
