Looks like a solid mutable inspired rack!
I personally don't think you'd need Plaits AND TelHarmonic -- having had both, I would go with TelHarmonic. That's not to say that they are the same, they certainly aren't. However I personally found Plaits to be kind of boring and not something I reached for. One thing I like about Make Noise is that they break it out where you have control over everything. Plaits is nice if you want to have Gameboy Sounds, but otherwise... meh...
Regarding Mutable, I might also suggest checking out some of the 3rd party builds that shrink the modules down to 8hp. Rings and Tides could both be found in 8HP and remain just and functional and accessible.
You have a Wogglebug and so I don't think you'd need Marbles, unless you really want staged out random voltages, which is of course fine if that's what you're going for. You wont need two Links... Chances are you wont even need one. I would go for Mults instead.
Not sure why you have 2 quad VCA's, again I'd go with Intellijel over Mutable -- better build quality IMHO.
That all being said: At the end of the day it's your rack! You might have a vision / sound in your head and based on who you are into, you might have insight into why you built the way you did! When I started, I based my rack on what was already existing -- Verbos Performance, Make Noise Shared Systems, and PGH Modular Systems. Very linear in patching, VCO into Filter, into VCA, Envelope, Delay / Reverb, out, before I started doing the gymnastics! And then it was a matter of figuring out which VCO, Filter, VCA I liked, fit and could acquire! Modular is largely about the journey, and sometimes we forget that there is a destination -- you'll get there! I can also promise you that what you are starting on right now... while almost be nothing like what you end up with!
Happy Patching!
