ModularGrid Rack

So this is the second iteration of my starter rack that I have poster before. Apart from what I ideally want above I already have a mother 32 and a dfam. I produce more ambient/leftfield leaning music. I have focused on utilities ( some of them I already own and absolutely love). I have realised that I need more mixers since i end up using triplatt and tangle quartet as a mixer more than a vca. I am not firmly set on an STO as a second osc (since I like domino by eowave too even though its a little too acidy) so would love to know if there are other options that allow more modulations.
