if your goal is primary Sounddesign, there is much missing.
in this racksize, to much modulation
(your bottom row is gone for modulation.)
the Captain O is redundant if want to process extern synths otherwize its just another modulationsource

if you dont are on a small budget and must rely on Behringer stuff, there are other incedible options, at least for the Sounddesign part.

You may focus on either junction or abacus or the doepfer adsr and drop the rest.
same for waves or four lfo.

the sounddesign capabilities of this rack are very limited.

you may look for modules which combine several ways to process audio in one, like waveshaping, saturation, filtering, delay, feedback and so on.

Also a nice filter for pinging.

if you want to go the low budget route, you may get a much bigger rack for the big sized behringer clones.

but I would invest in 1-2 more high quality modules for Sound-Design.

like Malstrom Wyvern (Filter+ Saturation) or intellijel Sealegs Delay, reverb, saturation)

Thank you so much! So if I understood correctly, you recommend centering on a single function generator module, add another filter beyond Swords, maybe going for a larger case (like those Behringer go ones I understand?), and add modules that expand the rack's sound design capabilities. Is there anything you recommend besides Wyvern or Sealegs? Thank you so much!

Limited high-quality audio output processing, No Sequencer, Missing Texture space. Can use more VCA (random, chaos), distortion, Bit-Crush, FX, Stereo/multi-output for monitoring and capturing better quality.

Much appreciated!! Are there any modules you recommend for those uses? I'm specially intrigued about texture and the lack of good audio outputs. As for the sequencer, I intend to use this system with a couple of Korg SQ-1s, but I'm definitely interested in something like a Steps/Stages.

Thank you! I'm slightly confused because I have a Making Sound Machines Multiplikand and a Takaab 2MLT. Do you think I should add a second Takaab?

(edit: the screenshot is wrong but if you click on it it leads you to the actual rack)

I make industrial synthpunk. My goal is building a eurorack synth for sound design, like generation 1 pokémon cries, complementing the Behringer Grind and Behringer K2 mkii I already have+offering extra utilities for them, and running the audio signal of my non-modular synths through it. Rhythmic stuff and live performance are not a priority, but I have a couple of Korg SQ-1s lying around.

What do you think? I'm considering replacing the second 3xMIA with a filter or maybe an effects unit. Maybe I'm missing something important that could take those 6hp?
