Your setup seems quite comprehensive. One could perhaps imagine some complementary Lfo modulation source, possibly more 'disturbing' (Ochd, Diode Chaos, Triple Sloths...) or other modules. But obviously this is not really the fundamental problem.
Fluctuations in inspiration are things that commonly happen. And they are not always dependent on the musical equipment. Advice: recharge your energy within the music you love. Then resume your work from these bases. Reflect about how to reproduce some references in your own way. All the creators, whether in music or in other fields, all including the most admirable and innovative, have started from what already exists, then appropriating things their own way.
PS: and take your time to experiment... sometimes also without thinking too much! Venture, avoid only out > out :))
