It is possible, but it will not solve the problem.

When saving customizations, customize does not actually read the
customizations in the .emacs. Instead, it deletes *all* of them, and
then saves all those customizations it knows about.  If the user has
added or changed customizations meanwhile from another Emacs instance,
those customizations will be lost.
