Why not at full size? And why at full resolution (which you hint at when you suggest a quality as low as 80%? I think you're right - 80%90% will give substantially smaller file sizes with no impact on what you see, but by limiting the file size to only 2048 x 1365, taking down a 36mp image to 3.8mp is a bit extreme, don't you agree?
I was thinking of the "archive" aspect of the request, where of course, full-size would be the same thing in the conversion from RAW. I may have filled in my own words / misunderstanding in reading the request for help ... The magic of LR is the export is a software function. If you don't like the result, just tweek a parameter or two and do it again with no risk to the original image files.
