Could you add a hook_package to uc_shipping (similar to hook_shipment) with ops 'delete' and 'save'?

This is what I was thinking:
-Adding module_invoke_all('package', 'save', $package->package_id) to the end of uc_shipping_package_save() function.
-Adding module_invoke_all('package', 'delete', $package_id) to the end of uc_shipping_package_delete() function.

Thanks for the consideration.
