I'd want modulation and utilities - you may not think you want them now - but you probably will find you need them down the line - maybe go and do some research! this is where modular shines in my opinion
On top of that I would look at the size of the case and abandon it if you have not already bought it - get a bigger one - TipTop Mantis is generally best bang for buck, but the large behringer may change that when it appears - if portability is a factor, then the mantis is probably better - the new case looks significantly better than the original
However, saying that, what you have already selected looks like it would generate some harsh noise, to me

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