I suggest you look at the modeling method using a combination of the mask tools with the connection of alpha and Gizmo. I like it for its simplicity and results.
If you are interested in this method. Here is a customized brush for applying a mask and three archives with alphas for falloff.
Unpack the archives into the alpha folder in Nomad. Move the brush to the tools folder.

Three folders with gradient falloffs.
In the DGradFalloff folder there is a gradient from the top edge to the bottom, in the GradFalloff folder - from the middle down. In the UGradFalloff folder - the gradient goes from the middle in both directions in a mirror way. I tried to repeat falloff based on existing ones in nomad.
Numbering goes in each group from left to right and from top to bottom. I only replaced the direct second one in the plate with another. So it turned out there were twenty alphas in each group.
