Can you write a Cordova package for Meteor?

Is it possible to write a Meteor package that is a Cordova plugin as well? For example, am I able to write Objective-C and Java code in my package that will be executed when run on a Cordova device?

I have only seen packages have dependencies to Cordova plugins, not actually house the plugin in the package. So does this mean I would have to write a Cordova plugin first, publish it to the Cordova library, when write a Meteor packages that depends on it?
