There was a thread about making your own NTv2 files in April 2011.
It may be easiest to generate a new NTv2 file in ASCII format,
and then use an Australian program to convert it to binary.
Some posts from the thread:

Now that I understood how to use the NTv2 gridshift file provided
by swisstopo (chaining transforms) I'd like to evaluate feasibility
of producing a _new_ NTv2 gridshift file going straight to WGS84
latlong rather than CH1903+ latlong.
How could I proceed to compute the shift ?
