Personally, I think the Heir of the Forbidden Jutsu, might be better off without the Fobidden Jutsu.  For example, was the the Forbidden Jutsu the reason her clan was destroyed in the first place?  A black widow is killed because it is too powerful for it's size.  Better to start with a fresh start and not have to worry about people coming after her.   Even if she did rebuild her clan, how would she know it wouldn't be destroyed again with the forbidden jutsu?  Though there maybe another route to rebuilding her clan.  Perhaps she could become a battle maiden.  Then her descendants could have the men take their last name.  Though she would need a teacher for this.  Perhaps Naruto Nara could help with this.

The crippled one from the Star training, perhaps Naruto Nara could train him.  I've heard of people in wheel chairs getting their blackbelts.  If they could get through a blackbelt test perhaps he could be able to defend himself.  If his leg is weak, then the rest of his body will have to become stronger.  For example, I think that he ought to learn to stand on one leg for extended periods of time.  Perhaps bo staff training would be of benifit to him.  As alot of it would be useful with a crutch.  So what if he can't be a Shinobi?  I cannot go into the military.  So one must do what they can.

The Shining Star of her clan might be better off not being a Shinobi.  A shinobi's life can be quite short.  Perhps she can aid her clan in other ways.  For instance, perhaps she would be better off as a priest.  She would have a more prosperous life.  Also would not be in the danger.  As it might be best not to risk her life needlessly.  Indeed if there are fewer members of her clan it maybe best not to put her life at risk.  Being a priestess she could also help not only her clan, but her community as well.  It would help them regain their status.  Naruto Nara some of what he knows.  I think his sagejutsu may even help her medical condition.

One thing is if the Kitsu were to give Naruto Nara training and a day of choosing.  I think he would choose the name of Akodo Tendo.  As he was adopted into the Akodo family, he should use it.  Also Tendo, was a kitsu who certainly never really liked humans.  He never forgot what humans did to him.  But he was the first to forgive them.  He served his Lord as was proper.  He also respected his prey when they didn't respect him as a hunter should.  The spirit of Tendo also has a special hatred of the Tsuno.   

Something Kubuto should remember is that, Lord Orchimaru has said that "it is impolite to sneak up on someone who outranks you."  While I do not agree with Lord Orchimaru's policies, in this matter I agree.  So if Kubuto were to go see the Leader of the Sparrow, he may wish to keep this in mind.  As it would be rude to try and sneak up on him.   The Sparrow choose him to lead them, so technically that makes him a feudal lord. 

Though his medical ninjutsu may be of some use to the Leader of the Sparrow.  As it could aid many of his clan and others.  Though not being a Shinobi, the leader of the Sparrow clan cannot sneak into places.  Nor should he, as it would not be fitting for even a minor Daimyo of the weakest clan to do.  It would be best to meet in a neutral location.

Also he would like very much to prove his theories.  Kabuto would be useful in this matter.  As the Leader of the Sparrow clan always wanted to validate martial arts theories.  For example, the Leader of the Sparrow clan has been offered a million dollars for his cure for Schizophrenia.  If Kubuto could help him to prove his cure works, then they could split the money, with the Leader of the Sparrow clan's half going to the Sparrow clan.

It would be best for Kubuto to send the Leader of the Sparrow clan a Letter, Email, or other correspondance.  It would be good if there was some way the Leader of the Sparrow clan could communicate with Kubuto.  Also Lord Orchimaru, ought to be very nice to the Leader of the Sparrow clan.  As it would be in his best interest to court him.  After all, the Sparrow clan may be upset if anything were to happen to him. 

Another thing is that right now the Akatsuki are more of a threat to both the Land of Rice Paddies, and Land of Fire.  So it is in both parties interest to work together for the moment.  Though I think Lord Orchimaru is pursuing the wrong strategy against the Leaf Village to begin with.  Instead of trying to DESTROY the leaf village, he ought to be either making it obselete or transform it.
