Is there any way to pass a modified json file back into this generator? I'm looking for a way to make small adjustments, or even have this tool re-skin something I've generated separately. New to this whole platform so I'm not sure if there's source code available.

No way to do it, sorry, but you can try loading a modified json in one of the editor which support this format.
