A multi-module for basslines and effects

I have limited space in the case and need modules that can occasionally become effects/utilities for processing external signals, but when needed, the case should also function as a classic system for generating sounds without relying on external sources. Currently, I have: Expert Sleepers EX, Disting EX, Melotus Versio, Librae Legio, Ampla Legio, Tymp Legio, ALM Pam Pro. I’d like a module that could be an excellent bassline generator when needed, but could also serve as an effect/utility when required. I had been considering the Virt Iter Legio (I really like NE modules), but I have some doubts about its effectiveness at low frequencies. I’m open to any advice—thanks!
