Protobuf isn't too complicated, I've found the wire format docs to be some of the best among the avro/msgpack/thrift/etc competitors.
Maybe you mean something besides the wire format. In that case, good luck, because that shit ain't protobuf.

Naming's hard :) Being really pedantic, I think even Google calls the schema description language "Protocol Buffers" and uses phrases like "the Protobuf binary format" or "the Protocol Buffer wire format" to refer to the wire format. Colloquially, it's never confused me to just use "Protobuf" for both.
You could be writing a linter, a formatter, an implementation of the Language Server Protocol, a compiler that's not protoc, a way to apply semantic patches to large numbers of Protobuf schemas, or any number of other useful tools. There's clearly at least some demand for tools like this - partial implementations of most of these exist, often with some corporate backing.
Unless you're implementing a Protobuf runtime (google.golang.org/protobuf in Go, upb for Python, etc.), your experience seems unusual to me - most developers I've encountered read and write the wire format using one of the existing runtimes.
That said, it does sound like a lot of fun - especially if it's in lisp!
