In cooperation with Andy E, this is the dark side of the force:
var _old = jQuery.Event.prototype.stopPropagation;
jQuery.Event.prototype.stopPropagation = function() {
this.target.nodeName !== 'SPAN' && _old.apply( this, arguments );
};
Example: http://jsfiddle.net/M4teA/2/
Remember, if all the events were bound via jQuery, you can handle those cases just here. In this example, we just call the original .stopPropagation() if we are not dealing with a <span>.
You cannot prevent the prevent, no.
What you could do is, to rewrite those event handlers manually in-code. This is tricky business, but if you know how to access the stored handler methods, you could work around it. I played around with it a little, and this is my result:
$( document.body ).click(function() {
alert('Hi I am bound to the body!');
});
$( '#bar' ).click(function(e) {
alert('I am the span and I do prevent propagation');
e.stopPropagation();
});
$( '#yay' ).click(function() {
$('span').each(function(i, elem) {
var events = jQuery._data(elem).events,
oldHandler = [ ],
$elem = $( elem );
if( 'click' in events ) {
[].forEach.call( events.click, function( click ) {
oldHandler.push( click.handler );
});
$elem.off( 'click' );
}
if( oldHandler.length ) {
oldHandler.forEach(function( handler ) {
$elem.bind( 'click', (function( h ) {
return function() {
h.apply( this, [{stopPropagation: $.noop}] );
};
}( handler )));
});
}
});
this.disabled = 1;
return false;
});

Notice, the above code will only work with jQuery 1.7. If those click events were bound with an earlier jQuery version or "inline", you still can use the code but you would need to access the "old handler" differently.
I know I'm assuming a lot of "perfect world" scenario things here, for instance, that those handles explicitly call .stopPropagation() instead of returning false. So it still might be a useless academic example, but I felt to come out with it :-)
edit: hey, return false; will work just fine, the event objects is accessed in the same way.
