Qlik Sense can binary load a qvw, which will pull in the table model, but not the UI. I know that's not what you asked but I wanted to clarify that item.
QlikView and QlikSense cannot currently "share" UI elements. The Qlik Sense Dev Hub does provide a simple tool that converts QlikView UI elements (Dimensions, Expressions->Measures, Visualizations) into Qlik Sense UI. But it's not fully automatic, it's a workbench/design tool that always requires some tweaking after conversion.
