No, no and no...

it's very very wrong to do so! (Okay, I'm being slightly jokey, but I'll explain why)

First and foremost; classical occult literature does not deal with these planets because they technically don't exist yet! and now pluto isn't a planet of course! Classical literature deals with the 7 classical planets. Most classical literature is based on neoplatonic philosophy, or at least relies quite a bit on it. Therefore you have seven planets, the heavens/stars, the firmament and then God or the 'Prime mover'. Yuo don't have other planets.
Second of all, modern wise occultists do not use these planets. The reason is VERY briefly included in the works of a early 20th century occultist and naturopath called 'Franz Bardon'. He states, as a small sentence in one of his books (I wont bother referencing, you can just trust me or go and read the books!), that the outer planets do not have a direct effect on Earth and our astral sphere, so therefore are not included in correspondances or 'sympathies' of our planet/sphere. Outer planets are therefore not seen as having an influence on anything 'sub-lunary'.
Also, Kabbalistically, you cannot show the outer planets on the tree of life. The tree of life symbolises everything and is a map of every correspondance... so they cannot have correspondances. They may correspond to other things, but do not have direct correspondance on herbs plants or materials in occult thought.

The attributions you see here are not grounded in occultism, but probably the 1960s new age movement which of course do use the outer planets, trans-saturnian.

Hope that helps!?

Take a look at Magical Incense by Dave Lee. He has the attributions in the back for all the planets and it's a great little book for incense too.
