Help me clarify my thinking on my rack

I keep going round in circles! I have a small and slightly motley selection of modules and semi modular:

2hp pluck Monsoon clone Spring reverb Lyra 8fx Tiptop wavefolder Dreadbox erebus v3 DFAM

Lately I am interested in textural, sonically interesting, lofi psychy stuff. I generally see the rack as creative FX really.

So where do I go from here? Everything I think of, I can already do, to an extent.

Envelopes? The Dreadbox can do that. Delays? Three things can do that! LFOs? The Dreadbox has two. Oscillators? I don't think i really want to get into building synth voices with all the expense and complexity that would bring.

So what would be some ideas for things that could unlock some extra potential here? I feel like functions and slopes and stuff might be a good way to go?
