I'm curious to hear what you have to say about crystal. Isobu hasn't displayed anything even remotely 'icy' about it. While Coral Palm seems awfully similar to Crystal Release. Just because Isobu lives in water doesn't mean that if it has an advanced/combined nature, Water has to be a part of it. Ice Release makes the most sense for Saiken to me, both visually and thematically and in relation to slowness and Ph based attacks.

The reason why I chose Scorch Release for Kurama is because of 'Kitsune, mythical yokai demons, are also associated with will 'o the wisp, with the marriage of two kitsune producing kitsune-bi (狐火), literally meaning 'fox-fire'. Scorch Release kinda has this will 'o the wisp look to it and it fits a Kitsune which Kurama is.

Well, unless proven otherwise, Six Paths Senjutsu is the only thing that gives one TSB. The databook states that inside of the TSB, the user can merge any natures together for different effects, so those who can use TSB should logically be able to merge any natures even outside of TSB, thus can also use advanced/combined natures.
