As EdLoach said, in principle you could use the standard OSM editor to progressively delete streets, getting backwards in time and having screencopies or exports at each step.
Anyways, I *definitely* recommend not to do this before having got some practice (what about improving your village map? I'm sure there are some details missing: stairs in the old town, streetnames missing...) because otherwise there is a HUGE risk that you inadvertently save your work (of progressive destruction), which would be a real pain here indeed.
So, sincerely, just don't consider doing this until you have indeed some experience with the editor (at least you'll have understood *adding* new streets is difficult ;-)
