I am looking for one or two modules to join my LRMSMSLR for coloration of the mid and side signals.

Space is tight, no more than 8hp, so it must be small module(s).
Must provide 2 ins and 2 outs with independant processing.
CV is not a priority.

Currently on my mind are
* Happy Nerding Tritone
* Feedback Modules PRE BX or CR x 2
* Noise Engineering Kith Ruina

Any recommendations?
Other suggestions?
Thanks
