Is it possible to create a Go module as a fork of a data-only non-Go module?

For example, given the following non-Go repo with only data files:

https://github.com/org1/repo1

is it possible to create the following fork with go mod init as github.com/org2/repo2, and Go code with embed directives:

https://github.com/org2/repo2 ?

I’ve tried doing this and received a lot of errors attempting to import github.com/org2/repo in another module, e.g. github.com/org3/repo3 along the lines of the following:

% go mod tidy
go: downloading github.com/org2/repo2 v0.0.1
go: github.com/org3/repo3 imports
    github.com/org2/repo2: github.com/org2/[email protected]: verifying go.mod: github.com/org2/[email protected]/go.mod: reading https://sum.golang.org/lookup/github.com/org2/[email protected]: 404 Not Found

More generally, what is a way to created a module to embed data files in another non-Go repo while maintaining ability to merge upstream changes (for data files)?
