Would it be possible for someone to edit this 3D file for me?

I'm not that good at 3D programs but I was wondering if someone could help me out here. I recently found a program called pepakura and it is amazing! Only problem is I want to make one of the Faceless masks from Pink Floyd's The Wall. I was going to use a preexisting file of the Borderlands Psycho Mask and was gonna use it as a sorta template and edit upon it to make the Wall mask well I just cant seem to findout how to edit it! Could someone please help me and make it I've been trying to make one of these things for literally years lol... your help would be a life saver... I've attached a picture of the mask I'm trying to make as well as a link to the pepakura site where in the gallery if you search Borderlands the Mask pepakura file you can use as a template will show up! Thanks again so so much!
