FeatureLayer with EXACT same symbolgy as on the REST? Or possibility to create scale-dependent donut-effect?

[nadja]

We're creating a webmap using the ArcGIS API for Javascript 4.25. We wish to include a FeatureLayer where all categories are styled according to the attached files. the symbology there was created with ArcGIS Pro and could be summarised as follows:

• one attribute defines the color, another defines the outline (seems to be posible)
  https://developers.arcgis.com/javascript/latest/api-reference/esri-renderers-UniqueValueRenderer.htm... 
• one attribute defines the outline
  this appears to be possible: https://developers.arcgis.com/javascript/latest/api-reference/esri-symbols-SimpleLineSymbol.html
• the feature blending
  this appears to be possible: https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-FeatureLayer.html#blendMod... 
• the scale defines the fill-type
  this appears NOT to be possible: https://developers.arcgis.com/javascript/latest/visualization/best-practices/scale/#scale-dependent-...
• donut effect: 
  this appears NOT to be possible
• scale-dependen generalization of the displayed features
  this appears NOT to be possible

We REALLY need to stick to our symbology, crucial are the scale-dependent symbolgy which not only influences the color and outline, but also switches at a certain scale from filled to donut-effect. Is there any possibility to include ALL these requests into a unique value renderer? thus I managed this: https://codepen.io/nwp_nadja_bernhard/pen/qBKoPqN 

(a MapImageLayer would display the layer in the desired format, but we can'tuse a MapImageLayer as this format doesn't allow to:

• search its features
• display a popup whith a hover/mouseover
• highlight the selected features

and these are functionalities we would need.)
