Translate these two Japanese words?

Question:

For my Japanese story I'm using a thing called a Spiritsoul. (I just want a Japanese word for each that I can put together. Ex. If spirit were taco and soul were shoe then thte word would be: Tacoshoe.)
How would this be said in Japanese? (No Kanji or Kana required, just Romaji)
Would Kirei be acceptable?
Would Kamirei be acceptable?
Would Seishintamashii be acceptable?
Would any other combinations of the above be acceptable?
Anything else?
ありがとう

Answer:

You can't just combine 2 words. It would be awkward sometimes. Japanese language is not that simple.

Any of those 3 you gave us here does not work.
