Actually Zbigniew has been doing this for the FMC for some time now. 
He called it something like "ZB version 2". Check out his solutions:

http://www.necrophagous.co.uk/cubestation/fmcresults/fmcsearch/search
.php?who=Zbigniew+Zborowski&metric=htm&lo=0&hi=99

Actually what he's doing looks like this:
1. solve FD and BD edges while orienting all edges
2. solve 1x2x3 at LD and RD using L,U,R
3. ZBLL

It doesn't look like he's posted anything about this on his site 
(though it may have changed since I last checked). I don't think he 
intends to keep it secret though, if he did why would he post 
solutions where people are inevitably going to analyze them? :)
