I’m going to see if @steelgoose 's odd shaped board holes will work for this. In theory it may (I don’t think the mounting holes need plating). As you say the pads are to close to allow a hole to be used for the tabs.
Edit: Nope, doesn’t look like it will work. Over and above that the slots didn’t make it, the pads are misscaled (perhaps because they are too small) in the gerbers. Maybe someone else can figure out a fix.
