I believe this is already possible, by using Mozilla's XPCOM interface to the SWT.MOZILLA variant of the SWT Browser widget.  It's just not very well documented.  For a taste of what's possible, here is a snippet that talks to some of the XPCOM interfaces:

For the EclipseCon e4 demo, I had a bunch of _javascript_ implementing a simple "Problems View" using DHTML and XHR.  Identical copies of this code ran in a real browser, talking to a remote Eclipse REST service, or inside of a SWT Browser in Eclipse, talking to the in-process Resources model.  The basic idea was to provide a custom implementation of XMLHTTPRequest in the Eclipse case that talked to Java by passing Strings back and forth.

The problem with this approach, I believe, is the footprint you get from creating many instances of SWT Browser, but I might be wrong on that. Maybe someone from the SWT team can correct me if I am wrong.

Bottom line: What you want may already be possible with SWT, today.

May I ask where you are going with this?
