I've had this idea brewing in my head for some time now, but was only recently able to get the parts I needed.
A couple of disclaimers: I'm very much an amateur customizer, on top of being rusty. This is more of a fun hobby for me as opposed to something that is worthy of sale like some of the fantastic customizers here. Plus, my new camera is still not the best. Oh and the stupid date stamp was on and I didn't feel like retaking
That out of the way, may I present the Sinestra Sisters!
(Click to enlarge, I'm challenged)
The heads are from WWE's Bella Twins. Turns out they fit perfectly on a MOTUC female, and the skin tone matched Catra. I did some very slight painting on the faces, darkened the lips, added dark mascara and gave them ice cold blue eyes to kind of make them look a bit more "evil".
Everything else is Catra. I painted the outfit mostly black leaving the bracers and boots as is. The black and red color suited the backstory I have for them. I tried to write it in the style of the MOTUC bios, and I will admit writing bios is tough. it ended up being much longer than a standard one.
UPDATED: New Bio!
I liked the idea of having some Horde badguys that serve Horde Prime. There's some potential for neat characters there I think.
A few other pics:

Thanks for looking
I have also added a few new figures later on in this thread
