I would recommend maybe re-thinking the value of Plaits. 2 Plaits would be kind of non-helpful. I recently made a new Eurorack friend and we correspond enough to have agreed upon the fact that modules that do 1 thing great are better than modules that do multiple things great. But not to digress, Plaits is a digital, and quite limited in its capabilities, and IMHO kind of junk. They sound thin. That being, here's some great modules to start building
2 AJH MiniMod VCOs or 2 Erica Synths VCOs. No, they don't have 20 settings, and no, they don't have a LFO mode, but they sound great.
Intellijel Dual ADSR (Intuitive and stellar performance)
Intellijel Quad VCA (You will need more VCAs than you think)
DivKid Ochd (8 independent organic sounding LFO's)
Maths
Either Intellijel Metropolis or Make Noise Rene 2 for a sequencer
Expert sleepers Disting MK4 can do all the effects you'll need for starting out.
