Sure, with:

  (use-modules (gnu) (guix profiles))

  (define package-specification->manifest-entry
    (compose package->manifest-entry
             specification->package))

The advantage of using package names like this is that it’s less
sensitive to module changes; the disadvantage is that it is not as
precise, particularly if there are several packages matching a given
name.
