Opinions on building this stereo...

So I'm building this rig to do big stereo stuff, both ambient and more traditional:

And looking for opinions. Here's what I'm thinking about:

1. Adding an offset/inverter utility like a tiptop Miso. All my LFOs are unipolar.
2. Adding a sound source to do ambient, with stereo reverb/delay... I hear Clouds is the go-to here?
3. Something to do stereo mixing... or more VCAs and use those?
4. Adding something weird to build up a stereo field. No idea here.

The biggest problem I have right now is, I think, lack of mixing or stereo field. I quickly run out of utility trying to mix right and left channels separately. But I'm not sure what problem I'll have next.

Any feedback very welcome!

1. yes good plan - also take a look at the happy needing 3*MIA
2. clouds is good...
3. both stereo mixing and more vcas - grab a veils if you can... also seriously consider a matrix mixer - leverage your modulation into more interesting territories
4. auto-panning (can be done easily with vcas, though), delays - use 2 different mono delays 1 for left 1 for right (the auto pan them with vcas), different reverbs used subtly on each side to give weird spatial presence

The biggest problem I have right now is, I think, lack of mixing or stereo field. I quickly run out of utility trying to mix right and left channels separately.

then address point 3 first

But I'm not sure what problem I'll have next.

that's half the fun discovery of issue and then work out how to solve the issue...
