Hello,
My first instincts tell me that I'd want more envelope generators/function generators and a reverb. To accomodate that, I'd first consider removing either the Plasma Drive or the Rabbit Hole since they're both tube distortions and relatively large modules (perhaps some redundancy there, but I have used neither so I don't have the remotest idea of how they compare to one another - I would personally want to go for trying the Rabbit Hole). The Performance Mixer MKII is also very large and may be overkill for this size of case, but it could still be a good purchase in the long run if you plan to expand later. Perhaps you could start with a smaller mixer and still use it as a submixer later on if you do expand into a Performance Mixer MKII and more cases and/or a bigger case.
I don't know how much experience you have with eurorack, but if you're just starting out, I would recommend against buying everything shown all at once. I personally find it more satisfying to learn a small set of modules really well before expanding them with others, which can quickly become overwhelming and/or lead to more shallow uses of more modules rather than more interesting uses of fewer modules (kind of like a "quantity versus quality" argument but more focused on personal knowledge and experience of modules, if that makes any kind of sense). Starting with a smaller set of modules will also show you what really interests you and what you feel like you're lacking. If you buy everything all at once there is the chance that you may end up with redundancy or excess of some functionalities and lack of others that you wished you had more of. I started out into eurorack with a Make Noise Shared System Plus and realized soon after that it was lacking functionalities that I wanted and had several modules that I just didn't personally mesh with. Today there is only one module in that system I like using that hasn't been replaced by something else that works better for me. If I were to restart today, I would have started smaller and picked individual modules myself.
All just my opinions, of course, but hopefully you find some of that useful.
