First system -- Enough utility?

Hey y'all, so like the title says I've created a goal for my first eurorack system and I'm wondering if there are enough function modules? I want to make sure I'm not forgetting anything in the design but I'm pretty new to eurorack so I definitely could have.

The idea is to feed the Morphagene into the Nautilus and Mojave to granularize and restructure non-melodic recordings into glitchy ambient noise, which would then have a gnarly bite added with the Rabbit hole. The maths is for envelope shaping, I would pair this with an external drumsource (thinking the drumbrute impact). The Octagain would mix and provide VCA. I've managed to cram a mult right in the middle, but might swap it with the Divkid OCHD for more generative motion. I'm really happy the modules I was looking at all happily line up to the 108U standard.

Am I forgetting anything?

I would reconsider the Octogain: it's a ART/Polytip (or whatever they're calling them now) module, which is meant to integrate with other Tiptop modules from the same line so it's kinda wasted potential (and it hasn't been officially released yet). If your main signal path will be morphagene->effects then you only have one pair of stereo outs to worry about and 8 mixer/vca channels seems kinda overkill. I'd definitely look into a smaller mixer/vca combo and add another modulation source/utility. A matrix mixer would also be really powerful in this rack because you could redirect the flow from one effect to another, feed them back into themselves and reorder your signal path. Looking at the Rabbit hole, it's a summing mixer, so be aware you'd be losing the stereo image from Morphagene and your effects (find a way to do parallell processing or an alternative stereo saturation/grit module).

How are you planning to integrate the drumbrute?
