Any possibility of converting skyboxes?

[b0rd]

Unity, or at least the few old Unity games I've decompiled (with permission from the original devs), seems to use a 6-sided cubemap for skyboxes. The images are each separate, which theoretically makes it good for scripts, but the images themselves are semi-transparent. The only working tool I've found to convert cubemaps to panoramas doesn't seem to like this, and I don't think Godot would work with it either.
Admittedly I don't have much experience with how Unity's skyboxes work, but Is there any possibility of a future option to

• Append or at least print the skybox's background color from the Unity project settings
• Convert the individual sides into a single panoramic image?

This may need to be a separate package, but either way it'd make things much more simple.
