What about simply deleting the old graph and loading the triples of the .nt file into the graph afterwards? I don't see any benefit of such a "tool" - you could just write your own bash script for this if you need this quite often.
The s-put tool that comes with Fuseki (or just doing a HTTP PUT to the SPARQL Graph Store endpoint using e.g. curl) does exactly this - replaces a graph with a new one in a single operation.
In the original scenario, blank nodes can be a problem if you have them in your data. There is no way (at least not efficiently) to compare blank nodes in two graphs.
