Rings would probably be a good call.
A resonant filter bank might also be worth a look, like a Serge ResEQ or the Erica Synths one. A dual/quad filter arrangement (like QPAS, Eowaves Tempetes Magnetique, or the Xaoc Belgrad) might also work. There are lots of options for both, so take a look around.
Be sure to balance modulation and utilities (both playable and flexible) with the effects so you're getting the most out of each module.
