Well, right off the bat here, there's two modules that are either discontinued or have supply chain issues with essential parts. These are the Grids (discontinued) and the HN 3xVCA (delayed due to no VCA chips). The Piston Honda might also fit there, as there was a great deal of confusion in the past couple of years as to whether or not The Harvestman's designs were going to remain available, and even though it lists as being in production here, this is one that either may require a possible substitute or you could simply go with a different wavetable oscillator. I wouldn't have gone with a Pam's here, either...given that the Rene mkii and the Make Noise Tempi have backplane connections that step up both of their games.
As for the layout, it's actually pretty user-hostile. I could whomp out a new iteration of this, but some of the module choices that've already been made are ones that ultimately contribute to that problem. Definite examples are the older Noise Engineering modules (fairly illegible panels...no fun at all if you're playing live and in a dim light situation) and the Zlob modules (same problem overall + very tight layouts).
Lastly, if there's a definite industrial spin to this build, I don't see anything that can really smash sounds up to get them into a more brutal area. For more industrial percussion, also, I would suggest Moffenzeef's modules, or something more synthetic that then gets run through one of Schlappi's audio manglers. Remember: back in the early days of Industrial, people were using a bunch of Roland stuff that they'd then munge up, and those Rolands were the more electro-sounding ones (TR-808, CR78, etc). Given that, you may actually find it MORE useful to get hold something along those lines, as the end result costs far less than trying to build drums into a Eurorack build, plus you get a lot of space in the cab back by doing this. It also helps that there's reissues of many of these, such as the Roland Boutique series or Uli's clones of the original 808, 909, and 606.
