Can I get to the paint below the current color

My car was originally F8 Green and was changed to its current color which looks to be FJ5. A couple of areas like the hood hinges and an area on the fender near the headlight you can see the old color due to the paint coming off. Since my car still does retain its original drive train I would love to some day get it back to its original color, My quaestion is is there a way to get the current paint off to see what the original paint looks like underneath? If its possible it would be a huge job since the color change was done to the engine bay,trunk and door jams as well.....Just a thought.
