I have seen a few swaps done... I dont think they were forum members.... Leather looks good but it is tough to get the same leather that normally comes with the touring package. Now if your looking to do something custom for your door inserts Alcantara/Ultra suede are good materials to use. They give you great wear protection along with a multitude of colors. It really comes down to what you want... If your looking for a certain theme leather may be the way to go or even Ultra suede... In this aspect of your build its best to know what your end game/look is so that we can give you the best advice.
The touring models use an ultra suede material so if that is what your going after we can do that.
Give us a little bit more info so that we can help you better decide
