These circuits always make me thing of the good old days of DIY noisemaker insanity, back when learning about building started with the old Harmony Central guides, before Guitar Center ruined that site. Those 3ms knob covered, garage painted junction boxes always fascinated me and I'd love to revisit them.
My top picks would be the Atoner, Noise Swash and Phaseur Fleur. Any would be great though, aside from the already verified Fuzz Jade which looks awesome!

I'm such a sucker for anything with a Resonance control that goes into self-oscillation territory.. it makes every pedal on your board interactive with each other. Love it.
This phaser looks really nice. Thanks for the layout, Alex.
Just wondering why you used 100k for the Blend? The BOM at 4ms lists 10k. Does a higher resistance make a difference?
