Look for some of the deluxe horse and rider Lord of the Rings figures from the early 2000's. They were made to fit figures that were pretty close to the DCUC scale. Toybiz was the company that made them, I believe.
They made a bunch like this:
A buddy of mine used them as a base for Marvel Legend's Black Knight, Valkrie, and Dani Moonstar.
Of course, he had to custom the wings from a few Marvel Legends Angels to do it.
Or you might want to just want and see how the MOTUC Shiftwind for She-ra turns out. We should be seeing pics of it at SDCC this year.
