Add Customized Language for Each Legend! Wattson in French, Valk in Japanese etc

They already have the content in the game with it being localized in dozens of languages. 

I think it'd be amazing if they added Language and Legend Specific Subtitle Customization.
They have it all recorded already obviously. 
But if they allows us to customize languages per legend we could have:

Wattson speak French

Valkyrie speak Japanese

Seer speak Nigerian(?)

Revenant German (for fun). 

Crypto in Korean

Etc.

 
I think this would be fun. 
And it would just add another element of costumization for each character.

Sometimes I've heard other language voices that sound better to me than the English ones. 

It would also just be a good laugh to hear different languages. 

And subtitles for any personally non native language would still be used so that you can get character call outs.

Or you could add so that the languages only change for you, and not for others. 

Or allow anyones language settings to be heard in your game. 

That mechanic exists right now, my French and Italian friends hear their game in French and Italian while I hear it in English. 
So it could work several ways without compromising comms for people who don't use Microphones.
