Brion:
In post #3 you suggest making a locked brummel in the loop. I don't think this is topologically possible if the loop is completed first. If you work with the un-looped line, obviously you can make your brummel eye in each end, and the bitter ends could be end-for-end spliced, but I can't see being able to make the end-for-end of exactly the right length (same as the standing part), so the load would all end up on whichever was the shorter section.

I like the idea of just making a loop, then forming the eyes and stitching the throats. This could be done with some tension from eye to eye, to assure equal lengths to each leg.
