Just now I think the next module may be dictated by price (quite possible the Tiptop Forbidden Planet VCF), I do feel I'm always running out of effects I like the Wash of sound that Clouds reverb gives but if Clouds is doing proper Granular stuff then I need something to help create that ambient smeared wash of sound.
A bit more pricey - but a Happy Nerding FX Aid XL would do a significantly better job of 'ambient smeared wash sound' than a filter

I do have quite a bit of modulation, Ochd, 2hp RND which I'm really enjoying for the random gate lengths to control the Freeze button on Clouds, Noise Engineering Clep Diaz, but you are right, I do seem to run out of LFO's pretty easily. And I need to do more about modifying their range (Offsetting, Full & Half rectification and Mixing them).
I'd concentrate on the multing and modification of modulation rather than adding more - shades, kinks and a matrix mixer (AI Synthesis for example), maybe a sequential switch and some passive mults or stackcables will go a lot further than a few extra lfos
I'd also consider Maths as being an interesting complex modulation source - especially if you work your way through the online manual enough times that you can patch program it without thinking too much

Utility modules are the dull polish that makes the shiny modules actually shine!!!
