What the previous NaPTAN import missed was conflation of bus stops with
existing OSM ones. I still occasionally find "duplicate pairs" in
Nottinghamshire. To gain general approval I suspect that any new import
would need to explain how the merging of the two datasets would take
place - I can think of places where NaPTAN's correct and OSM not, but
also vice versa. However, I can see a few obvious "quick wins" (e.g.
bus stops in unsurveyed remote areas).

Obviously, given that it's continuously updated, consumers have the
option to use NaPTAN bus data _instead_ of OSM. I believe that this is
what Traveline do (they're certainly active on the GB list; not sure
about here - they may be able to add more detail).
This does prompt another question - post import, what plan would you
have for keeping the data in OSM updated when NaPTAN data changes?
For info, see also this recent thread on the forum:
Another possibility rather than an import might be to find a way of
making the NaPTAN data a more easily-accessible resource than it is now,
and letting mappers update OSM, much as happens now with road names,
using tools such as http://ris.dev.openstreetmap.org/oslmusicalchairs ?
