Not sure what to suggest other than widen the nut slots and set it up fully so it plays it's best in BEAD. I set my Dyna Bass for BEAD by just using a 5 string set I had and ditching the G string. Widened the slots with some proper nut files that I already had. Didn't need to adjust the saddles nor truss rod much, surprisingly.
a {} ^^This^^, pretty much. I had my LB-20 Carvin set up that way for a while - with Roto Tru Bass 88 Tapes. They've since been replaced with the 65-130 strings from a 5-er set of Roto 77 Jazz Flats. Anyhow; the two things that always seem to come up with BEAD tuning are: 1. A floppy B string. I don't know why this should be the case so often on a 4 stringer, - when it doesn't seem to be for a 5-er - but.. it is. The tape wound B string on the Carvin was.. tolerable, but IMO, just barely. The Jazz Flats B string is noticeably better... If you use a 5 string set to do this, you might want to get a set with (for 5-ers) a B string on the lighter side. Mine, as I say, is sorta OK - because the flat wound B is very stiff - but probably still too heavy.. 2. Intonation. Some 4 string bridges don't like trying to intonate a B string; some simply won't do it at all. And, some are perfectly OK with it. IIRC, a bent plate Fender bridge is usually an "OK with it" one. The Hipshot A bridge on my Carvin will intonate the B string, too - but only just... There's a BEAD Club around here somewhere; you might want to check them out...
I had a local Luthier setup my Ibby SR600 in BEAD, but rather than filing the stock nut, he made a new nut from bone so if I ever wanted to go back - I could. He did a great job, and also polished my frets for $60 which I thought was a good deal. I took it home, and gave it a new setup (relief, action height, intonation). I'd also suggest using 5-string sets because there are so many more choices than with drop sets ... unless you find a set you like. I've been using D'Add Prosteels EPS300-5 (balanced tension) set with 127T, 107T, 85T, 63, and throw the 43 G away. A $20 set.
