you probably don't need both the rcd and scm - I'd go divider and start with a faster clock - and probably add the expander for the rcd instead - which brings me to how are you intending to clock this??? where is master clock coming from?
not convinced that triple sloths and wobblebug are both needed in a case this size - I have both (well an erica swamp, which is a derivation of wobblebug) but I have about 7 times the rack space
decent start with utilities - but not much in the way of basic plumbing - I'd want more mixing at least - sub mixers and a matrix mixer would be good - that way you can reduce the number of your modulation sources and get more interesting modulation via matrix mixer - and you probably will find you need a lot more in the way of attenuators - really useful for controlling level of modulation
probably don't need the doepfer buffered mult and links - buffered mults are only really needed for pitch and you don't really have enough pitch outputs/inputs to justify both at the moment - remember the middle section of links can be a buffered mult too - I'd get some stackcables or headphone splitters for passive mults too - one caveat to this is if you are trying to use maths with a module that has a non-buffered input - sometimes it can stop working because of this - but only a problem that needs to be solved if and when it arises - I only have a couple of modules that this happens with and they are video modules
I'd also consider dumping the cursible - not enough modules to warrant it at the moment imo - and the bastl 'drone'mixer, again at the moment - bring them back in in the next case perhaps...
have you actually used an eurorack modular before? do you know how small the modules actually are? especially looking at the mutable clones here - the originals have good ergonomics - but the micro clones don't...
I'd dump the output (quite possibly not needed - & if you're going to get one get a better one from a company with a better reputation) and at least one (possibly both) of the mutes and the quad vca - replace with veils (saves 2hp) and get a better end of channel mixer (possibly with mutes included and based on feedback below)... how are you intending to listen to this?
I'd also think about mono/stereo mixing in here - go through working out what sound sources and modifiers are mono or stereo and how you are going to mix these both separately and together
erbe-verbe is huge and is mono input/stereo output - great module - but maybe not suited to a case this size!
hope this helps...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
