I think a King's Field mod/hack would be awesome, and from a technical standpoint, totally doable.
The "invalid MS DOS" message happens when you try to drag a STR (Movie) or XA format sound file off the disk. Both those file types store sound data in a special way- similar to a music CD. Windows isn't designed to handle data written in that format so it makes an error. On the King's Field(US) games, the ".S" files in the "OP" and "STR" folders are STR format movies.
Most of the textures in KF1&2(US) are in FDAT.T and RTIM.T. The ones I looked at were in a TIM format, but the header had been modified so they couldn't be extracted/edited by TIM tools. But, they have still have the palette with the image data below, and that's all you would need to edit for a mod. It would just take thinking up some fancy ways to insert the edited textures.
If you are actually interested in making a texture mod yourself, I would see if I can figure out an easy way for you to edit them.
This is a false color view of RTIM.T from KF2(US) that shows the texture image with the header/palette above.
