What you need is LESS. And less attempts to put too many functions into a small case would be a good start. Less sizable modules would also be good. And then, less of the "sexy" modules and more of the boring stuff that actually makes the other expensive stuff WORK.
One thing you DO have less of is modulation sources...and in this case, you need MORE. And as for VCAs, ANY would be a good move at this point, because there's not any now.
Get those drums out of there, for starters. Frankly, unless you've got massive space in your cab, trying to build up a "drum machine section" never works out nicely. The modules wind up being space-hungry, and also require a good trigger sequencer in addition to whatever else sequential you've got. Don't do this...get a proper syncable drum machine instead and lock it and the Hermod up to the same DAW clock. And why have Rings AND Elements when the latter has the former in it? Seriously, get some proper FILTERING...having a good, punchy LPF is key to making bass that wrecks subs, NOT a physical resonator.
There's a lot you might get out of https://vcvrack.com/ before trying this again. You need to understand what attenuverters, VCAs, logic and clock modifiers (ESPECIALLY if you plan on a lot of sequencer work), and so on actually do and how/why other modules NEED what they do. Also, the "go bigger THEN reduce rule applies here", like Garfield mentions; start with a rack that you KNOW is too big...because, in the end, you're going to find out that what you knew about that build size was 100% wrong. If you begin with too much space, you have room to scale back FROM once you have a module complement that you know will work. But right now, that last part is a real stumbling-block. Do some work to actually see for yourself how this should function, then come back to trying to do a hardware build. Your credit card will thank you later.
