lookup getter for host properties

Hi, while working on Opera 9.5's support for getters and setters, we've discussed whether it should be possible to lookup a getter/setter for a native (host) property. For example, something like
func = Element.lookupGetter('innerHTML');
// func is now a function that does serialization of nodes
func.call(document.body); // would return BODY's innerHTML
..or something like that. Or, to provide an example that stays within the ES spec instead of venturing into the DOM:
func = Array.lookupGetter_('length'); // func is now a function that counts array elements..
Is this something worth implementing and/or standardising?
Sorry if this is already covered by the spec or previously discussed.
define{G,S}etter/lookup{G,S}etter will not be defined by ES4 the way things look now, so all of that is outside the upcoming spec.
