If I was trying to do what you want to do, I would probably approach this rack with a lot more modulation sources and VCAs. If you already have a lot of guitar pedals/external effects, you could save money by picking up a decent external interface module like the Bastl Hendrikson or XAOC Sewastopol II, and using your pedals instead of modular effects (but that's not quite as fun). Obviously, we all approach things differently, and you will probably get a bunch of different recommendations than what I quickly came up with based on your example racks and description. As for me... If money was no object and I was going for a chord capable IDM-ish type rack with some random sequencing, glitchiness, sample manipulation, effects, and a bit of analog monosynth flavor, I would probably go in a direction like this. I'm sure I left out something glaringly obvious, but you know what you like and want better than I do.
