If you want more chakra to take advantage of Kisame's passive attack boost then try out Orochimaru with Kisame. Both are sword ninja so you can make them immune to conditions if necessary, which matters since Kisame can't heal if he's on fire. Orochimaru will provide you with free chakra every time someone dies. Clone supporters can help there and enemy clones feed your power too. Kabuto can even heal and cleanse while supplying them.
