I did just that a couple of years ago to test prefix delegation. I connected a second router behind my primary router and IIRC it got a /61 out of the /56 assigned to me. Of that /61, one /64 was routed to the local LAN of the second router. I presume the process allows for cascading routers until the /56 is exhausted, but I did not explore that. I was satisfied that I demonstrated prefix delegation worked.
