I suggest a 3 step process:

1- Add the new `modus-themes` GNU ELPA package.
2- Update the `modus-*-theme`(s) by replacing them with placeholders
   (labeled as obsolete) that depend on `modus-themes`.
3- Remove the old `modus-*-theme`(s) packages.

There's no hurry between each step, and we could wait a year or two
before taking step 3.

We could even have a step 2½ which replaces the `modus-*-theme`(s) with
packages which remove themselves after installation, so upgrading the
package would remove it ;-)
