AFAIU the initialization of each package is already defined inside each
package by the author. The way emacs's packaging infrastructure works
goes along the lines (see (elisp) Packaging Basics):

* At installation:

  - Search every Lisp file in the content directory for autoload magic
    comments (*note Autoload::).  These autoload definitions are saved
    to a file named `NAME-autoloads.el' in the package's content
    directory.

  - Byte-compiles every Lisp file in the package.

  - Add the package's content directory to `load-path', and evaluates
    the autoload definitions in `NAME-autoloads.el'.

* At startup:

  - Emacs scans for a predefined directory for NAME-autoloads.el files
    and evaluates them ('package-initialize' function). We could maybe
    exploit 'after-init-hook' or something something similar.
