Replacing vertical DDR4 DIMM-slots for horizontal ones

I'm carefully planing a very slim full ATX 1U build, with CHT (Cappilar Heat Transfer Pipes) or very custom water loop and rotary vane pump.
Custom cold + distribution plates for CPU and GPU save dozens of millimeters from the chassis height for bigger and more efficient radiator

But that RAM mountains are messing with me, I almost hate them.

Can I replace vertical DIMM slots with some of these without any issues on mATX/ATX motherboard?
1. 25 degrees angled
2. Horizontal or double stack options not found for DDR4.

it looks like the angled slots would need wider spacing on the motherboard than the traditional spacing of vertical slots. there are also extra through-hole mounting points with the angled dimms and those aren't present on motherboards not designed for them.

Any updates here? I am thinking about a similar build, and am running into the same problem... Were you able to solve this?
