I've had the carpet out of my car and think that if you can get the seats and console out, it isn't hard to remove the carpeting. The easiest way to accomplish this would be to swap it, but since there are no other factory colors (right now) you're going to have to make it.
The original carpet has a textured bottom made out of foam which allows the flat surface that's seen in the car. Making a template of the original carpet and installing raw carpet isn't going to look good, and will put the wiring and electronics attached to the floor art risk for damage.
However, you can use the original carpet as a template and make a perfectly fitting "skin" to go right over the original carpeting. The only areas that will need some additional work would be cutting pieces to cover the heat-molded areas over the console and undere the dash. These could be attached from the bottom using carpet seam tape.
