Expanding my rack - seeking suggestions

Hello dear modular enthusiasts,

One of my mates is expanding his rig and I am considering the opportunity to get his 9U 90HP desktop case to replace my current 6U 104HP skiff which would give me an additional 82HP to play with.

Here is a link to the rack: https://modulargrid.net/e/racks/view/3186553

Id probably add a decent mixer, Muxclicer and Stages to start with but still being a relative noob to modular, I am open to suggestions / thoughts / comments on any modules you would add to this particular rack and why ?
