With the first statement being, "don't do it anyway", here's what I know...
Lacquer is "hot" (lots of volatile carrier), so it could make a mess over enamel is that isn't very old. But with a good primer, it should be fine on older, fully cured enamel. Enamel would almost certainly dissolve a layer of lacquer before it solidified, as it takes forever to fully cure. I imagine there could be mush as a result.
I have been lucky the few times I did some striping on an enamel car, using lacquer to get a very thin profile.
