Personally wouldn't do it to mine, but I have a buddy who put Vintage Air in his Z so he can drive it year-round in comfort. Very discreet installation, uses the original firewall heater cutout and VA's air distribution box is the same size and appearance to the GM heater/blower casing, so there's nothing that can't be undone later on. Must say, it makes cruising possible in our daytime summer weather down here, rather than sticking to vinyl seats and dehydrating, so I totally get why he did it.
