`package-input-rewriting' (documented in [1]) can be used for the
purpose:
--8<---------------cut here---------------start------------->8---
(map (package-input-rewriting
`((,emacs-minimal . ,emacs-package)
(,emacs . ,emacs-package)))
package-list)
--8<---------------cut here---------------end--------------->8---
