Cant say that I have ever tried this method and don't think it would be all that great as you would still have the color and contour of the siding to contend with. If you give it a try show us a picture and I'm sure there will be some more input. I have tried to use computer generated doors and windows which after making a frame for the right size they did not look all that bad (from a distance) would not recommend this technique for front row models. Hope this helps,Pat
