   I expect that some of the work necessary to make this possible will be done as part of [AIP-42](https://github.com/apache/airflow/projects/12?card_filter_query=task+groups).  
   
   That feature lets you take a list of _n_ items (in XCom, say) and tell Airflow to create _n_ tasks for those items.  The task group part of it isn't done yet, but when it is, you'll be able to have it create _n_ task groups as well.
   
   Seems like scheduling the execution of the nth task group in an expansion would use much of the same code as rerunning a task group.
