I used SM400s and SM900s for years in rehearsal spaces and on backlines, and I can't see how using a BBE will get you to that tone. I did have access to and tried BBE processors over the years and never really felt they helped - and I've got fairly hi-fi basses.
The baked in preamp tone of the Fusion 500 may even fight the BBE a little bit. Isn't that amp designed to mimic that tube sag and saturation which goes against everything the SM series SS amps stood for? I would think a better option would be one of the older RB heads, instead.
I think some BBE processors were a bit of a tone-suck when bypassed or "off" too. So there's that as well.
I know a lot of people who swore by BBE processors dumped them as soon as they saw/heard Hartke XL cabinets because those gave them much more punch than the BBE processor could ever give them.
It's kinda weird reading about these now - in 2020 - I remember they were all the rage years ago with people trying them in home-stereos, PA systems, and I think there was even a tiny BBE processor you could link into your car stereo for a time. Wow... memories.
