It is true that you have many sound sources here. But depending on the style of music you want to develop, and the final use you make of your modular, one can conceive or remember that this is the lion’s share. So that’s OK with me.
I often propose analogies in my comments: you own a lot of colors for your paintings, and to highlight them you need all kinds of tools like brushes, knives, sponges, masking tapes, etc.
When we equip ourselves with utilities and modulations (see the famous @JimHowell1970’s signature), we expand our possibilities. And this can even become excessive, or addictive too... So for your future addiction may I suggest, among many others, the little following selection:
Divkid Ochd (so much ‘organic’...)
Xaoc Nin (for your Zadar)
Happy Nerding 3x MIA (as already suggested)
Xodes LB5 (easy logic, absolutely useful and harmless)
Doepfer A-151 (classic quad sequential switch)
Intellijel Planar2 (it is you who become the utility)
And in any case: the Expert Sleepers Disting mk4!I believe there is also a lack of filter modules in your setup.
From Doepfer filters to the great Joranalogue Filter 8, the choice is vast to complete your lonely QPAS. Without forgetting a proper Low Pass Gate.As always, should you or any of your tracks, patches or videos be caught or killed, ModularGrid will disavow any knowledge of your actions :)

Thanks lots for all the helpful suggestions!!! All very helpful and will be considered seriously... I will think about how I can fit in more modules into this rack without spilling over into 15U! I make experimental music, industrial and ambient sounds, and I am enjoying this transition from semi-modular gear to modular! :D
