Another way would be to move to Abmin for a moment and then, from there, to its parallel major of Cbmaj (enharmonically equivalent to Bmaj). I think it could be quite smooth specially if you go through the V64 --> V progression (B/F# --> F#).
For example:
I guess this couldn't be considered a lush progression, though. As @Monarcheon suggested, for a lush progression it might be better to start with some line (maybe melody, or a strong bassline that you know points towards B major, or both) and start filling in the remaining voices in any way that sounds good.
