Most likely not - PDFs usually use decent compression algorithms, especially for grayscale or black and white images. One thing you could do is sync your library to the cloud using Sync Library->Sync to a cloud folder, and then your band mates can just sync to that folder and it will pull in all 10000 songs. If you need to limit this to just the new 10000 songs, use Settings->Library Settings->Switch Library to set up a temporary library first that you can clear later. Alternatively, you can use Sync Library->Sync to another device to just sync your device to theirs over WiFi, which would be faster.
