Proposal for massive tag renaming for statues in UK

Hi,

Many statues/busts/memorials in UK have outdated tags. For example you might see a lot smth like this:

historic=monument

memorial=statue

name=Equestrian statue of the Earl Roberts

wikidata=Q21286417

or:

artist_name=William Behnes

artwork_type=statue

building=yes

historic=monument

While correct tags must be:

historic=memorial

memorial=statue

name=Equestrian statue of the Earl Roberts

wikidata=Q21286417

So I was thinking about writing a Python script which will automatically convert all statues/busts with outdated tags to:

historic=memorial

memorial=statue

So, would like to kindly ask for your ideas, pros/cons other suggestions on the matter. Thanks.
