I think you have all what you need. anything more will be luxury and G.A.S.

but if you have the money

Filters:
I like bastl Ikarie - 8 hp stereo filter with drive
or Winterbloom Neptune

Mimeophon, Nautilus or Sealegs could be an idea depending on your taste.

Morphagene or Nebulae

for great sounding percussion, SSF Ultra Perc is the shiiiit in my opinion

for dark stuff - SGR 20 from Knobtechnology
its my favorite new toy. Its a analog vco, noise maschine , Industrial drum voice, drone maschine
The vco is a variation of the buchla triangle and it has some buchlataste in it.

I think the SGR gives a new special flavour and im a big fan of it.
Sry if this goes to far, but I just want to share my euphoric

get a SGR 20 😁
