I like that idea...
Notepad works great for such a thing, changing a desert region to a snow region by changing the name of the texture, and looking at all other gas files that have that same texture. That's pretty much how I did my map edits, even reversed the starting point and made em run backwards.
Yes Notepad is a very useful tool, probably even better than the more advanced "Notepad" clones as it's so simple and uncluttered.
When I created the extended regions for LOA and DS2BW Adepts, the editor would paint the new terrain with default textures. Before I discovered the trick to applying them properly in the Editor I used to open nodes.gas and find/copy/paste the texture in texsetabbr for the new nodes. As you say this would still be the easiest way to mass replace all the textures in a region.
There are limitations to this method but at a glance there's up to 15 texture sets that could be used for DS1 nodes. I'm not sure how many there would be for DS2 but it looks like around 26 texture sets.
I briefly tested making a new region and populated it with the starting regions from the Utraean Peninsula (all blank with no objects). I haven't gone any further yet or attempted to stitch them together.
