Aravi 
I made her a custom race so that she can have her spotted fur without requiring me to make all the other Khajiit in the world spotted. It was actually a lot of work, but enlightening on how these things in the Creation Kit interact.
I'm trying to think of where to put her in the world. One idea is to have her follow Kharjo's caravan. The other is to make her a random encounter as you travel on the road.
EDIT:
These are the tutorials I used to make the custom race:
Creating a custom raceGetting custom textures to workRead the second tutorial when you get to "Add the required Armour and Armour addons" in the first tutorial if you have custom textures.
I created a new race from scratch for Persephone. It was a lot of work. Especially creating a new headpart for every eye color, every hair style, every eyebrow, etc...
Those were good links you provided. The first one especially goes into a lot of detail. I used it when I created my Deadwalker race for Persephone. It helped me with creating the armor addons for the hands, feet, and head.
Putting Aravi in Kharjo's caravans sounds like an excellent idea. Or you might put her in Castle Dawnguard, but that would require having the DLC active all the time (I keep it on all the time for all my characters, but I realize you might not want to).
