I have gone down the originality route before when I restored a Mark two Jaguar and it becomes a monkey on your back. If what you do is tasteful, appropriate, suits you (sir!) and does not in your view detract from the overall idea of how the car should look then just do it!
When you come to sell the car you can show that it has been loved and is a Little better than your average.
At the end of the day, condition, history and price will dictate whether or not you sell. This is my opinion after 4 brandies. I will probably get back to you at about midnight when I have had 7 or 8. The views I express then may not necessarily concur with this post.
