That tight Chuck Rainey tone is not something easy to dial out of a Streamliner, whose tone is more "fat and gooey" to my ears. If you're set on staying with a Streamliner, you might check out an Empress Para EQ pedal. It includes an adjustable Q factor to help tighten up the tone is selectable, sweepable frequencies. It also has a boost button for some overdrive.

None of these tonal issues are related to the Super Midget or BB2. Both of those cabs reproduce what you put into them. Your challenge is further up the signal chain - not at the end.
So tough to use an incredibly well produced album like Aja as a base line for tone. Most likely Chuck recorded that direct and they added a little compression in the mix. So much of that tone is the fact that he is so tightly locked in with the kick. I think you'd be surprised what sound like as an isolated bass track.
In any case, if you have an amp that requires a Para EQ to get the sound you want then IMO you've got the wrong amp. Reminds me of when I had a Markbass LM2 and tried multiple cabs before realizing the lower mid bump couldn't be dialed out no matter what. FWIW, I've been using an GK MBF800 for the last year and it sounds amazing on every gig with a range of cabs including a BF One 1o.
