In a word no it can't be (simply ie without getting your hands into some code) done as weewx stands now. The way I think of it is weewx is fitted 'for but not with' generating plots(images) over an arbitrary period (ie a user specified start and stop) . Essentially what is needed to do it is there (after all wee_reports can generate a report as of a specfied timestamp). If you were keen and with a bit of analysis of wee_reports (its not that big or complex) and reportengine.py you could achieve something along the lines of what you seek.
As for whether weewx will provide that functionality that's one for Tom, though I suspect there are other fish to fry at the moment.
