Not in a reasonable and reliable way no. There is a tool called ktexport
but it has severe limitations (really meant for importing keytabs into
the Wireshark packet sniffer). The Samba guys have "vampire" code that
I think can do what you want but I don't know much about it.

Also, note that SPNs are mapped to accounts and you really want the keys
associated with accounts. So keytab entries for cifs and rpc would have
the same key.
