I do want this in SMBX and I feel like I know how. First, It uses all of the backgrounds that SMBX uses but it is on a slant that you can change and also move. Also, the sky's hue can also be changed.

To make a background like you've shown there in a level, though, is pretty simple. It just requires some basic glDraw code and simple mathematics.
