yes it's no problem if you're organized.
Actually making the 12 templates per day and submnitting them will be hard if you handsubmit unless it is only a list of 30-50 TGP's, but it means you will be working 16 hours+
If you already have the templates, and crop the pics in advance it is no problem,
then you could make 1000's of galleries, upload them, generate the pages with recips on each day and bob's your uncle
