To each his own, and all that stuff. Personally, I've never heard a Schroeder cab that I actually liked. Aggressive midrange is cool, of course, if your particular playing situation calls for it. But at the end of the day, it's still supposed to be a
bass. Some actual low end coming out of the cab from time to time would be a very nice thing to have.
OP, don't mess around with the ML or the DB, or even the PH. For gospel, you need hi-fi cabs with some real polish & refinement. Your previous idea of getting a pair of fEARful or fEARless 12/6 or 12/6/1 cabs is a very good one. Be sure you don't overlook a Thunderchild 12 (or two), or a pair of Acme FullRange cabs either.

I guess I would push back on this a bit. If the OP's tone goals and playing style are as I assumed previously (and I think he said they were), I would avoid the Acme cabs completely. They are great, but REALLY don't do well with slap transients... not good in that situation, and the massive low end can get in the way without some good control, which many amps don't have. Very low efficiency also... they need more power than you would think IME.
I love my Thunderchild cabs very much, but the top end is very pure and relaxed. If you like your Ken Smith or MTD or J bass to grind a bit up top, and have that nice 'top of the driver' sort of upper mid response, and a bit of top end sizzle that floats above the cab, that might not be the best choice. The new TC212 is pretty cool though, and is kind of a 'better Acme' (i.e., much more robust drivers to handle digging in and peaks, big low end but not extending into the sub bass, and, for better or worse, a VERY clean, pure, balanced top end that is 'present' but not sizzly or aggressive).
fEARful.... can't STAND the voicing of that mid driver combined with the low crossover point myself (I had a fEARful for a short while). The fEARless seems to be a possible option, since the voicing is tightened up a bit and the top end has been 'fixed' a touch, but again, a mid driver loaded cab has its own tone. If I was going that route, I'd go with a Thunderchild... smaller, more even voicing, etc.
Assuming the OP doesn't need massive stage volume, is at least on some kind of budget, and cares about size and weight, and kind of digs the Norm Stockton, Andrew Gouche sort of tone, the little GK Neo112(II) x 2, especially with the MB500 head, is probably the most cost and weight expensive way to get there.
There are rigs I like even more (for example, the new Bergantino CN cabs, which are just as light, and put out more absolute volume and have a VERY high end crossover that just sounds amazing), but for the value and this particular application, hard to beat that little GK rig.
IMO though... most good players can make most rigs sound very good for anything, even if the voicing of the cab or head is not inherently voiced with a particular tone goal in mind.
