This is quite frustrating. We are all hanging our hopes on a third party community, i.e NifTools when it really should be Bethesda that does something. They've really only done "half-a-job" with the creation kit since there is currently no Viable method of creating custom meshes, and importing them into the game engine. Scattered reports of one or two people who have managed to make it work, but also who either don't really know how they did it, or aren't willing to share the information. I was actually going to write my own tutorial on it, since i have worked a method of getting meshes into the game but have since hit on major issues with creating collisions. So my point really is that we should be leaning on Bethesda and asking them to finish the creation kit properly, OR at the very least update the Wiki to tell us how they did it themselves.
