Personally I have always wanted a fully chrome bike. But that's just me.

You have several options. I don't think anything would really decrease the value, and what does it matter anyway, if you're going to keep it? Make yourself happy before anyone else. Repainting it would be a solid choice. Keep in mind you'd probably want to get rid of that rust first. But by painting it, you could always strip it back to chrome. Option two would be to just remove the surface rust. This can be done several ways, and I think you best do your research. Many people will tell you to use super fine steel wool, and I have seen some fabulous results. However, others argue that you are damaging the chrome by doing so, and will undoubtedly post some online guru that swears you're removing all the layers of micron thin chrome! But I'm not going to start a debate. Your third option would be rechroming. If I had the money, I would choose this route. However, it is very expensive.

Hope this helps. Beautiful bike you have there.
