Liberator of Wraeclast Supporter Pack

Is it possible to buy the Liberator of Wraeclast Supporter Pack and only take the art book while replacing the hoodies and T-shirt for points

the way I'm going to do it is being the supporter pack beneath it, exchanging the physical items for points then upgrading and sending them an email saying I want the book rather than points


haven't done it yet tho so dunno if it will work probably will.
