Modules to complement my Moog Sound Studio

I have a Moog Sound Studio with
* 1 x DFAM
* 2 x Mother 32
* 1 x Subharmonicon
* 1 x Labyrinth

I want to expand this with Eurorack Modules to experiment different modulation sources and I want to add more flexibility. I already bought an additional 60 HP case and an ALM Pamela's Pro Workout. I could expand with another 60 HP case, thats the limit (apart from the money of course). I did put my current ideas in a rack named "Wishlist" but these are just my current thoughts.

Which modules do you think I need to complement my Moog semi-modulars? And why do you think so? I am open to any suggestion.

I would add some effects, a nice delay or any different kind of effect you like; a wavefolder; envelope and LFO module & 1-2 multis. Do you use an external mixer? Pams Pro is always great.
