Define "true locked brummel".
If you mean such that the 2 strands are interwoven (marlin splices I believe they are called), then the manner that I have altered Opie's steps fits.
If you mean that the 2 strands have to also lie along the standing part as in the locked Brummel for a fixed eye, then the answer is no for the simple fact that there is no longer a standing part.
