A couple of small tweaks to your new rack.
Here's your latest rack.

Though some modules appear to be missing here.. clicking the pic shows them.

You can get an even SMALLER versions of the uOrnaments & Crime and Temps Utile. They are 8HP... what you have are 14 each. I'd go with those so you save 12HP! The 8HP designs are pretty standard so you can buy them from a maker. I have a guy on the forum that I've used. I can pass that along in private message if you need someone. Take a look at Michigan Synth Works if you want to buy from a retailer.

You have up to 6 gate/trigger sequencers in Temps Utile and up to two CV/Gate sequencers in O&C. You can probably do away with the Steppy unless you're looking to make a lot of changes in real time. I'd wait on the Steppy if you get the Temps Utile first.
