Yes but the rendering stops a the Part-Bounderies so inside the
Part-Instance you'll have to decide in which UI-Technology you are
running and your (SWT)Java-Code is executed. All the framework passes
you is a part you can draw your self on (for SWT a Composite, for Swing
it would be a JPanel, for JavaFX a Parent, ... => this belongs to the
rendering engine creating the workbench layout).
If you want to see none SWT in action I can point you to:
https://github.com/tomsontom/e-fx-clipse/tree/master/at.bestsolution.efxclipse.runtime.workbench.renderers
who implement the rendering using JavaFX, but naturally then one also
has to implement the inner stuff using JavaFX as well.
The code in https://github.com/tomsontom/emfdatabinding-tutorial is a
bit older but you see there the same UI implemented 3 times. I've
started long ago a project called UFaceKit which would all to write such
forms once and run under different UI-Systems but that didn't made to
final stages.

The compat layer translates extension points like view, editor, ... into
model elements but not SWT.

I'm not sure about which trick you are talking here. draw2d is normally
only part of the area Eclipse 4 has handed over control to you custom code.
