I can't help you for getting below B, but just getting there was a journey for me.
I am a low-end player at heart, I almost never used the G string, I felt the D string fretted up higher gave me better tone and sustain, and I always felt constrained that I couldn't get low enough, so I was a natural for switching to BEAD.
I ended up doing a full setup for it, which really helped. Bought my own nut files and string height gauges (those things are fantastic). All I did was file down an existing nut, so not that hard to do.
But then I had a big problem, I do church music, and the B string tone wasn't a good fit for that genre, I was a bit horrified at how it sounded at first, it really stood out as the string that didn't belong. Enough that I was considering going back to EADG.
Eventually I added a high-pass filter (~70HZ), then ran that through mild compression, and now all the strings are balanced, punchy, and tight, with lots of sustain when I need it.
And even with the fundamental removed the low B sounds great, harmonics are a wonderful thing.
