Doom 2 textures in Doom 1

I want to know if you can put all textures from Doom 2 into The Ulimate Doom game?

You have to copy the textures to your WAD but if you do that, yes you can. The only problem will be that the new switches won't work.

I believe that if you were to take the Doom 1 textures and put them in Doom 2, though, that the Doom 1 switch textures would still work. Correct me if I'm wrong though.

There's always the SWANTBLS animation/switches editing utility, though.. That is if you are going to be using a BOOM-compatible engine.

Yes, they will work. Doom 2 even requires all of them or it will crash. That's why some unused ones are dummies in Doom2.wad.
