So you want plugins to have the ability to *change* the exception that 
is raised? It shouldn't be very hard to modify onTestFail to do this - 
perhaps a .exception attribute on the event.

If this is set to None the exception is not reraised and the test 
becomes a pass. If it is changed to a *different* exception, which could 
include SkipTest of course, then this will be raised instead.

Would this work for you?
