First of all, if you're considering pairing this with a 2s, go on and get the Rackbrute. You'll be much happier with the resulting form factor, and you'll also find that it "gigs" better because it's much easier to transport both this AND the 2s as one unit.
Second, that's one expensive DFAM you've got there...because you're housing and powering it TWICE. Once with the skiff Moog put it in, and the second time if/when it gets stuck in here. Don't do this. Not only does this BURN UP 60 hp that should be used for devices that don't already have power and a case, you've also not added something like Erica's MScale to correct certain "discrepancies" between Moog and normal Eurorack CV behavior. This is also likely a huge part of what's keeping you from using a Rackbrute 6U.
Then beyond those points, I can tell you right off that what you have here isn't going to work like you think it will. The entire build is missing submixers, attenuverters, and so on. And it's also majorly lacking in modulation sources, which are essential to getting these other modules to do what they're capable of. You CANNOT build a decent modular system without sufficient modulation sources. Period. And that, minus utility modules = unworkable expensive box of circuitry.
If the idea here is to pair this with a Mini 2s, a far better way to proceed would be to figure out ONE MAIN THING you want this to do...either an actual complement to the 2s, or a sequencing addon, or...well, the upshot is that you can't make a small build like this do loads of things. Pick a lane for it and keep it there. And then, any functionality you get beyond that...that's gravy.
One other piece of advice...you still seem to be in flux about where you want your music to go. And if you're trying to build a modular without that key piece of info, you're much more likely to wind up with a box of costly bits...NOT a musical instrument. You're pretty well-equipped right now, tbh...my suggestion would be to get used to crosspatching all the stuff you've got NOW (especially the SE-02 + Minibrute 2s + DFAM combo) and getting used to how signal flow works there, what you might SPECIFICALLY need to take the present gear forward, and the like. And in the process, you'll have more room to sort out where a modular would work or even whether or not you really DO need one.
