Mythic+ and Ascended but for PvP gear???

I think that it would be nice to make some kind of way to get better/improved PvP gear just like they have Mythic+ and Asended gear in PvE.

So basically the Mythic/Ascended PvP gear that has a bit better stats than the regular ones that are currently available.
So a way to improve your current gear through PvP (BGs, arenas, World PvP).
Not drastical improvement but just something that you could have to work on so you could improve your gear stats a bit in PvP.

This would bring more activity in PvP in various ways.
