I don't particularly like the idea of combining with that high resolution texture mod. A lot of the textures look out of place, the image/file size and load time is way too high. I'm all for high quality art including high resolution textures, but it must be done in moderation. You can resize a 1x1 solid colour image to 4096x4096, but that doesn't make it any higher quality. You should also take into account other rendering effects, such as environment mapping, specular mapping, etc...but if you're going down that path, it might be worth using rend2 with physically-based rendering for realistic materials. For reference, the high resolution texture pack being discussed is > 1gb and IMO the ingame quality does not match the file size or load times.
