It is tempting all right.

The biggest obstacle is that at least one of those Pipelines requires
access to a clone of public-inbox.org/git, and cloning that is rather
expensive. Even a shallow fetch would be super expensive, by virtue of
_all_ the mails being blobs reachable from the tip commit's tree.

Further, GitHub Actions' triggers are a bit too limited: I want this
Pipeline to trigger when public-inbox.org/git is updated, not when any
branch in gitgitgadget/git is updated.

So yes, while it is tempting, it is also not possible right now to use
GitHub Actions.
