retry ansible failed task using callback plugin

Question

Here is my question.
I would like to retry a task runned from ansible-tower which failed using a custom callback plugin, however I don't even know if it is possible to perform this action using callback.

For now I'm able to print details about the job when it's failing... and that's all.

Here is my function which is handling the errors on each run.

def v2_runner_on_failed(self, result, ignore_errors=False):
    payload = {'state': 'failed',
                   'task_name': result.task_name,
                   'task_output' : result._result['msg']
                  }

    print(payload)

Having those information is fine but this is not what I excactly need.

Am I looking for something "impossible" ?

Regards,
Remy
