Are Large vanilla skyboxes possible?

[FARTbob]

Heyyyyyyyyyo,

I know people have done it with source ports before but is it possible to make a vanilla Doom 2 skybox made up of two or more images? That would be awesome. Any help would be greatly appreciated.

Thanks

Yes, TNT: Evilution literally does this.

DoomKid made a tutorial on this.
