It won't work. Nominatim stores different things in the slim mode tables 
than does the standard rendering backend.

That is not a problem, you'll just have to fix your "extents" in 
inc/datasource-settings.xml.inc and modify the osm2pgsql_projection and 
dwithin_node_way entities in inc/settings.xml.inc accordingly. But as I 
said above this will not give you the option of running the same 
database for rendering and Nominatim.
