It is possible but not convenient; you would have to write code to do
the decryption.

Nothing stops you from extracting a krbtgt key to a keytab.  It is true
that people do not usually store krbtgt keys in keytabs--but krbtgt keys
are also not normally NT hashes; they are normally random and do not
correspond to any password.
