Those right-angle SMD .1" pin headers are a bit expensive, as are the 8 LTC6090. But if this attempt works, it'll be a great foundation for further optimization.
Someone in the Discord chat thinks, that those MOSFETs will not be able to sink 375W through the thermal vias. Not sure if I agree, will have to test ... what's your guesstimate?

Google translate via the camera app has been a life saver when dealing the Chinese data sheets.
375W will cook the mosfets for sure. You have Rthjc=0.4K/W, this amount of vias should add another 1K/W or so, then you have TIM (HAL has very poor planarity so you'll need a thick layer). I would operate them at <50W dissipation TBH, that is if I were to use good active cooling.

And no ENIG either, it was completely wasted in the early stages of development ... will do that when it's final and RTM :)

Just add water to that concentrate!
