I'll be sure to talk to someone about that for you. I'm sure the site will consider your idea but we have a lot of other things to deal with first. Try this site for a Kinstone guide. Hope this helped! ^^
Aside from the fusions that are needed to continue the game, and the specific fusions that will always give you the same results I think kinstones fusions and what they give you are fairly random. In other words you can never really tell who you're going to fuse with and what you will get. Also, when you complete the game, there can be things that you haven't got I think even if you've made ever fusion. For example, in the area with all the fallen over trees, where each fusion lifts a new tree, you can get to the end of the game and still have trees blocking off whatever is behind them. So I don't know if a full guide is completely possible.
However, to any admin reading this, if there is a guide I would love to help as I have played through minish cap approximately 20 times and would love to contribute to the site.
