You can use an around advice, and have almost complete control.

Well, certainly unloading can have consequences; that's why I insist
that the best place to define what should do for any package is in the
package itself. Even an add-on to a package should just define its own
feature, and FOO-unload-function for itself, IMO. If you don't use the
FORCE argument, a package cannot be unloaded before unloading its
dependencies, so it is safe to unload the add-ons before.
