Mike, 

The major obstacle here is that each NIDS image will have its own projection.
So, to create a composite, you have to reproject them all to a common
projection. GEMPAK does not currently have the capability to reproject
an image, so that is the limitation.

I plan on looking at creating a program that will composite the NIDS,
but the other issue is handling areas where the radars overlap.
So, until then, McIDAS is your solution. Or, if you can live with
the 10km GRIB, you can display that as a national composite
product in NMAP from Grid/RCMG (eg, the HAXA00 KWBC product).
