Is it possible to use a 16gb mSD on the v1.2 Music Shield?

I know specs call for 2gb (shocked the 2.0 is the same), but is it possible to use a 16gb version?
Is there a fat32 library to use in place of the fat16 one?

Also the v1.2 shield has the head holes for the ipod connector…any place I can actually get that to sold on and have that as well?
