Speaking, for once, with my "MR Editor's" hat on, please
don't upload them here, thanks

We would just be repeating what can be freely downloaded from SP. All the books here are "hand formatted" whereas the SP books are machine-generated LRFs which really add nothing to the PG originals. Our upload policy is that books should only be uploaded here which add significant value to the original. Uploading SP books would be no more beneficial than uploading books from, say, ManyBooks.
