If you have already published your content on HP then NO, you can not republish elsewhere without major rework. Anything you put on HP has to be "unique" otherwise your HP hub will be marked as duplicate.
You can however use the content you have published on HP on other sites by doing the following:
(1) Delete it from HP and publish on another site.
(2) Alter the content including the title so that it becomes almost unique in its own right, that way you will not get marked as duplicate on HP.
