There has been a lot of requests for new Ghost voices. So how about on order to get the new Ghost we have to replay our characters origin mission! So instead of Dinkly bot having found every Guardian at the Cosmodrome, we get the option to replay our characters origin mission, with new starting stories and locations depending on the different Ghosts. Maybe we could then replay all the original missions with the Ghost having new dialog? It would be nice to have the option to give our Guardians different origins instead of everyone having just come from the Cosmodrome.
