Given the way that SOMA stuff likes to lie flat (the Lyras, etc) and work as both device and controller, I was sort of thinking the best way to set up a tandem with the build above plus the Pulsar 23 would be to put the Pulsar 23 in front, where a keyboard might go in a more conventional rig, maybe with some taller feet in the rear to rake the control panel just a bit. Then behind that on some type of riser (perhaps something like this: https://www.sweetwater.com/store/detail/MDS100--ultimate-support-mds-100-modular-desktop-stand) with a steeper angle, that would be where the Eurorack cab would be. That way, you can easily interlace the two devices, then the Stargazer could go to the left, Eventide box on the right, and that would make for a pretty ergonomically-friendly rig. One other concern, though...there's not really any sort of interfacing that can go from synth to line-levels, so whatever you're sending to the Space would be pretty hot for its front end. Alternately, you could add (somehow) a small stereo send/return module such as Ladik's A-525 to step down and up, and then deploy the Space box in more of an inline configuration within the Eurorack patch, instead of as a post-Eurorack device. Just an idea...
