A couple suggestions come to mind:

1) Add something like a DannySound CaliOsc + a Timbre or a Make Noise STO + an Intellijel Bifolder to get into some analog wavefolding and variation territory, I've been doing that with Random*Source Serge modules and really loving it.
2) Get a 4MS Ensemble Oscillator, tons and tons of stuff to explore in it from chaotic drones to lush synth strings.
3) Get a Tanh, don't change anything else and start exploring feedback patching.

Specific additions aside, the main thing that comes to mind for me looking at this rack is actually to set aside the Rings and to keep the Kinks. It's too easy to dial in good sounds with Rings which ends up making me lazy at least. Substituting it with something that requires more effort and skill will bring some of the excitement back into your patching, imho.
