I don't think so. Even though the combat steps are carried out you're not in the combat phase, it's still the questing phase so combat actions aren't allowed. I think the rules state explicitly that "X actions" can only be performed in the "X phase".
That's correct in Hama's case and with cards like Feint. If the action specifies a phase it can't be performed outside of that phase.
