Hi Reahjru !
If you are on iOS 5.1 or 6, this could work :
You could maybe try to use AudioCopy in conjonction with the AudioShare app. I didn't try it myself, but here is a possible workflow.
1) Load one of the loops you want to export
2) Use Copy All in the Tools sub-menu
3) Repeat 1) + 2) for each loop
4) Open AudioShare, AudioPaste your tracks
5) Use the various export options of AudioPaste to export, including mailing
I'm currently working on a send to mail function integrated in the app, so you should not need that in the future. Another option is to delete some unimportant song files from iTunes to free up some space.
Also, I'm in a trip myself, so I may not be able to answer quickly.
Have a nice trip

!!
