There is nothing particularly magical about cgGeoMossaic. It is not a
very sophisticated program. I can think of about 10 better ways to write
it just off the top of my head. It's a memory hog, for sure. I wrote it
one afternoon to do a particular job for me and thought others might
find it useful.

In principle, you could write a loop through your files, mosaicking the
n-1 output with the nth image. I don't see any particular reason that
wouldn't work, and if this is a one-off, efficiency is probably
overrated. You could delete the intermediate files that would get
created in your loop, unless you wanted to examine them for some reason.

The loop might take 10 minutes to write. It's worth a try as a first
step. Unless, of course, this is not a one-off. Then you will probably
want to forge a different solution.

Cheers,

David
