Variable chamfer/slope on solid quad-dominant meshes. Advice request

Hello all,
I am struggling to find the right method of implementing a controlled chamfer feature on thickened (solid) quad-dominant meshes. One interesting solution “for variable mesh offset” that was suggested by @DanielPiker, however, it does not meet my needs since I want “slope” to emerge at least 2 vertex rings inside from naked borders and also I’d like to have control over the thickness of the outer mesh border.
I think I got very close to the desired result using Stripper plugin, developed by @joncorrod, however it is quite difficult to implement vertex rings levels (using mesh strips) and my resultant mesh topology is open and invalid.


The final solid mesh needs to be quad-dominant since I want to further smoothen it in using Catmull Clark SubD.
I would be very grateful for any advice/thoughts on this! Rh/Gh files are attached (random geometry is internalised in Gh file). Stripper plugin is required to open the attached gh file (see hyperlink to the food4rhino website above).
