The only thing Inafune can do for IGA is to give him some advice about management or gameplay, Inafune's company is not a publisher per se, his company comes up with ideas for games and publishers buy those ideas, they don't have the people to program games either. If IGA wants to go the kickstarter route, I can see him asking for advice or even some kind of partnership to gain more notorierty.
If I was IGA, I will partner with Inafune for advice and Inti Creates for the development, they are a small company but they did a great job with sprite platform games, recently Gunvolt, or he can try the 2.5D route like Mighty No.9, but that requires a lot more money.
