@blanchsb If I understand correctly I think this is what yo are looking for.

Added some edge loops and changed the settings on the Bevel Mod.
Changed from percentage to offset at 0.1 and from weight to angle and adjust the angle until it looks good, ended up at 60d.
With this just need to keep an eye on the rest of the model, but usually its just a matter of adding edge loops or changing the angle of the face slightly by moving edges by literally fractions.
