I haven't done it myself, but I saw it done on "Overhaulin", it looked pretty cool. It does take some skill though to make it look like real chrome. Not something the average guy could do himself. Plus it would probably cost more than trim to pay someone else to do it. But you're right it won't require you to drill holes or fuss with getting trim to fit properly, or even finding good trim.
If you do it, make sure we get to see some pics of it when your done.
