removing the atlantis, if you don't use it much, seems like a good idea
I would personally go with either batumi or pam's in this size rig, not both, and add more utilities for mixing/modifying/multing modulations sources to create more interesting ones - kinks is great, if you can find one - discontinued recently, but there should be a few still in stores
re utilities in general doepfer and ladik are your best friends - just make sure the depth is ok in the case
I'd also consider an fx aid xl - lots of different algos for effects and decent number of modulation inputs
"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia
Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
