ham bones

Hi, newby here. I have a q. about ham bones (hocks). If I already used a couple to make ham-bean soup, can I reuse them to make a stock, or add them to a beef stock that is currently simmering? They simmered in the ham-bean soup for 2-3 hrs. so does that mean they will have no flavor or nutritional value left? Also, would they ruin the flavor of the beef stock? Thanks in advance.

Do not take risk. use for which it is made.
