Thank you all for replying. I really like those 1u rows. Especially the CV voltage source. It seems so handy. For my second case I will look into it. Now I will focus on this idea. I really dont want to change things up to much anymore.
After some research and great insights from the amazing Lugia I might go with the ES-3 Mk4 + ES-6 Mk2 combo. Cheaper than an ES-9 and it gives me 8 outs if I am correct? The ES-9 gives me more than I can use with my RME UCX (8 A INS). Let me know what you guys think of it!

All the best and enjoy the weekend.
