Headliner thickness question

[illuminaudi at comcast.net]

Someone on the list said not to replace a headliner with material thicker than 1/4 in., but can I use thinner material?  I don't see why not, but wondered if there were any BTDTs.  The material in question is a perf-leather-look vinyl approximately 1/8 in. thick with a felt-like backing.  I think this should be easier to apply without getting roller indentations in the headliner.

TIA
