Not sure wood is a softer material than vinyl (depending on species).
My concern would be the difficulty of engraving without the grain interfering with the groove.

While sustainably-grown wood can be an economical and eco-friendly building material, its relatively low tensile strength limits its potential applications. That could soon change, however, thanks to a new self-densifying technique for creating super-strong wood.
