Only with the ones that don't have mipmaps, which is much faster to figure out with Windows Texture Viewer - it will tell you on the display how many it has. As far as I know, Oblivion needs a minimum of 4. Unfortunately Paint.NET and GIMP don't seem to give you that much control and you'll end up with at least 9, possibly 11, depending on how large the original textures are.
Paint.NET is also the simpler choice to use. GIMP needs an extra plugin to handle .dds files.
