Suggestion: Becoming able to change the UI skin

For over a year now I've very much enjoyed, screamed, raged and exhilarated at what PoE was or has become. Like most I'm also very excited for the future, both in terms of what 3.19 as well as next years announcements on ExileCon in regards to PoE 2 will bring...
....buuuut (and you know there was a but because there's always a but) something always bugged.

MTX we can buy in the store allow us to customize our characters looks, our flasks, even auras and skill effects, but the one thing we're staring at for hours isn't customizable.

The interface.

Is there any chance, even as an mtx, that we'll get differing interface types, looks etc?

We've seen over the years with the challenge leagues that there are numerous styles for new interfaces windows for league mechanics but little that changed the look of the general interface itself.

Even a simple reskin would be nice.
