Alternative to carpet

So I've been thinking about how carpet and the rubber mats hold moisture in and rusted a lot of floors.


So I'm wondering if it would be an idea to make the floor boards smooth, get rid of the ribs in the floor and really finish smooth the floor and use a textured paint or even bed liner in there so that if the floor ever got wet again for any reason, it would like hosing down the outside of the car and simply dry out and keep long term corrosion to a minimal.

Dumb idea or brain squirrel cage turning idea?
