While it's technically true that there are no plain numeric limits on
templates, in practice the high complexity of the EH listed building
templates (etc) imposes a practical limit - I'm not sure of the exact
level, but one to two hundred sounds about right. We hit this problem
fairly regularly with some of the larger cities, and I ended up
simplifying the templates to compensate a couple of times.
Being able to use WD-generated lists will be a very different
ballpark, but as that software doesn't really exist yet... ;-)

Your memory serves you badly, Michael. MediaWiki
imposes no such limit on
templates; The Wikipedia article Israel
(
https://en.wikipedia.org/wiki/Israel) has 452 reference templates, for
example. MediaWiki does impose a limit on the depth of transclusions and the
number of expensive parser functions, but those restrictions are unimportant
now that we can call a Lua module from within a template to do the same job
with much less stress on the server.
"List of rivers of England"
(
https://en.wikipedia.org/wiki/List_of_rivers_of_England) is an example of
how about 1500 geographical entries have been organised, so sheer numbers
don't necessarily present a barrier to creating wiki articles. As querying
Wikidata is not possible at present (and we don't have a date for its
implementation), I wouldn't recommend waiting for that before starting work
on the Grade II buildings.

Yes, we have all the grade II data for England and the corresponding data
for Scotland, Wales and Northern Ireland, too. However, getting that
information onto Wikipedia in a usable format is not trivial are there are
getting on for half a million building records.
Automated linkages between Wikipedia and the Monuments Database rely on
each record being represented by a template in Wikipedia, and unfortunately
MediaWiki limits the number of templates to no more than 130 or so (if my
memory serves) per page. That means breaking the records up into such small
lists that navigation becomes a nightmare. Even for the grade II* buildings
we have some areas that have been split into separate pages of buildings
based on name A-M and name N-Z. Such lists are totally hopeless for users
who need to find a particular building and know neither the name it happens
to have been give in the official listing nor even in which listing area it
appears (these are based largely on obsolete county and other regional
boundaries).
So, yes, it would be good to get these on, but some new approaches will be
needed. Wikidata may well be able to help in the future (eg by providing a
searchable Wiki database which is automatically linked with the various
sources of official data).

Andy,
Getting the photos CC licenced would be good, however most
counties/areas don't have lists of GII buildings (certainly not using the
template developed for WLM - although many may be too long for current
template restrictions). Perhaps any communication with EH could include a
request for the data & then the same semi automated development processes
applied to creating the lists (would make it much easier if GII are included
next year).
I believe we have the data, just haven't imported it yet to
Wikipedia
because grade2 buildings weren't included in Wiki Loves Monuments this year.
Now that Wiki Loves Monuments is over we could start importing the remaining
lists to Wikipedia. If lists get to big you just have to split them up. This
is how we did it in the Netherlands too. For example the city I'm from
(Haarlem) has over 1100 Rijksmonumenten. In the centre of the city this is
so dense that I ended up with several lists per street. All these individual
lists are for Haarlem are connected through a navigation template so you
don't get lost.
