SR4 Texture Mod?

Considering we already have a modder working on a Sr1 Texture mod for Saints row 2. I'm very curious to see the other end of the spectrum. having Saints Row 4 Or even just Saints row The Third's textures be modded into the game. Seeing as we will most likely NEVER get a proper remaster of 1 AND 2. AND the fact we already have both a HQ textured mod and an Enhanced Graphics mod...why not? :)
Nothing is impossible when it comes to texture mods. I would also like to see a Saints Row IV or Saints Row The Third texture pack for Saints Row 2.
Is that even possible to do without changing the engine? I mean, there must be a limit to the upgrades you can do.
well, that probably depends on if The UV maps from sr4 get brought over as well, along with their textures. If it's JUST a texture change i don't think it will be much of an issue for someone to do. at best it could probably slow down your game if it were done but you wouldn't have the engine be changed. but then again what do i know?
