I haven't done those yet because the prices for originals on BrickLink were still fairly reasonable at last glance. Although I'm looking at the prices again and it'd run around $60-100 for a full set if bought from US sellers. Maybe I ought to take a look!
My goal with selling the laser cut replicas and sharing the art is so people can relive the classic sets. They were a big part of my childhood and I hope they were and continue to be for other people as well.
