Would it be smart or stupid to download BIAB2016 into a BIAB2014 download-folder?

I was thinking it might save some gigabytes of download, since a lot of the realtracks are the same (as that archive is progressively growing)

My concern is that perhaps BIAB2016 would skip downloading updated realtracks if it thinks they have already been downloaded?

So, is it necessary to download everything as if it was a first-time install, or could I safely merge the download-files of BIAB2016 into those of BIAB2014? (at the time of download, not at the time of installation, which I understand is to be done into/on-top-of one's earlier BIAB-install)

If possible, we would only have to download those files that are actually new, and not the whole archive all over again.

Thanks
