Mirror Idea? What do you think? Options

[JRust]

Okay so I have been kicking around an idea for a while. I've seen plenty of different mirrors people have used on their doors. I've seen a few tiny ones more on the small window than the door. I'd really like to see something that is a bolt on but has an extra option to it. So here is my idea

I'd like to replace the small triangle window on the door. I would like to have a nice molded side mirror along the bottom of what used to be the triangle window. Then above add a smaller window that opens on a pivot. Like you used to find on older trucks to bring air into the cab. Not sure what they called that window but does this make sense? I have a picture of it in my mind but nothing on paper yet?

I am sure this will take plenty work. Just seems like it would be doable. Maybe I'm nuts but I think taking off the original window. You could fab up what was needed into it's spot on the same window channel? (IMG:style_emoticons/default/confused24.gif)
