For sure. Merge is the most basic primitive for creating metadata. If you are familiar with RDF, which uses Subect-Object-Predicate triples that's more similar to Chomsky's original X-bar theory which calls these triples Head-Complement-Specifier. The difference is that Merge sees the triple as a derivative of the merge primitive and X-bar sees the triple as the primitive. Both are about the fundamental nature of metadata or data linkage/relationships and how meaning is derived. Both can be applied mostly successfully down the layers of the language stack - semantics -> syntax -> morphology -> phonology -> phonetics.
