I am thinking about doing it. I have had the headlights apart before when I did the projectors. Really simple to do. Just make sure you have the 3 points that touch the baking sheet on some balled up tinfoil and some more sheets of tinfoil under that. I melted one of the holes that the plastic rivets use to bolt to the truck on the inside of the light :S. I set my oven at like 240 then baked them for about 9 minutes.
The tacky stuff they use to seal the headlights is a pain when you are removing the lens from the body. If you get it on the lens do not worry as goof off takes care of it though. Just follow the DIY in the sticky and you should be fine. I had never done it b4 so hopefully my mistakes help you out
If you need any more help just pm me.
PS Make sure you wear gloves
