If you could export to OSM format , that would be awesome.   Like in the 
way Overpass does this.

In pseudo:

- get data from osm (assuming here , the data is partial, so lets say, 
everything with an 'addr' tag in your field of view.)  , the same effect 
you have when exporting a certain key using overpass.
- get data from crab, craft is as such (preparse it) to facilitate 
merging with osm data set.
- Make the diff, but create an OSM compliant xml (with meta data, 
otherwise you won't be able to create a changeset from it)
- open the changeset with JOSM, verify, correct, validate and push.

So, truthfully, I think a tool like you envision is still interesting 
and the more we do, the better and less manual JOSM work to do.  But we 
need to do chunks of it, we should do this for small area's.    it's 
also easier to (later on) fix things that went wrong yet unnoticed, that 
way you don't have to deal with huge changesets finding that single node 
on page 450 (ever tried paging through changesets using the site ? ;-) 
.   Even a perfect full import in one go would give us headaches later.  
It keeps things managable

I think it's great you want to do this, I'm just not too positive about 
the success and it's not that I doubt your skills, it's that I doubt 
we'll be able to cover all exceptions that you usually run into in a 
decent timeframe.    The problem is not so much the bulk of perfect 
tagged stuff ,   but the ones that need special treatment.   It could 
turn out to be a bigger job than anticipated right now.
