Back about two to three weeks ago, I mentioned in a post that I was going
to try my hand at a Starwars-Ranma1/2 fusion, with the majority of the
characters miscast.

Well, I have about ten pages written, up to the meeting of the sand
people, using Genma and Ryoga as the droids.  However, I realized that
they really don't add much to the story in their roles.  Thus, should I
keep them as they are, or rewrite their parts with Nuku-Nuku and Eimi
instead? 

Also, what are the colors of the character's chi-attacks/aura?  I've seen
many different colors quoted in fanfics, and I'm at a bit of a loss. 
(Ideally, I'd like to find a blue attack or aura.  I plan to use this info
when they meet with the primative Smurf tribe much later in the future).
