Shouldn’t be hard to transform them.

I have some info on my (currently zipped up and not online) web site in connection with generating a nice postscript version of the original published GDW maps, but I haven’t looked at it in ages, let alone modified into something that might be usable. IIRC the program I wrote to translate them was written in whatever version of BASIC came with MS-DOS in the early 90’s, which was not coincidentally to the last time I had an machine running an MS OS on it on my desk. :-/
