Agreeing with Ronin.
Start small, and slow so you can learn what parts do, and what you'll need. I think the big sequencers are a waste if you're at home playing with a keyboard or a computer. That Eloquencer is a monster, and you can use a laptop and the ES-8 to do everything already.
You could start with Plaits as a big complex voice, and ONE module to drive it, Maths, Pams and ES-8 all can do a huge amount of control, and deserve your attention and practice, only after a few weeks you'll decide if you want a sequencer or the envelope generator Quadrax to be in your little rack.
If you're after 'a ton of eardrum damage' you should look at distortions or harsher modules from Schlappi Engineering or Moffenzeef. I don't see any crunchy distortions in your proposed rack.
