I need a more sutiable marine model file

[necron3]

i need the head changed on the marine modle to be bigger and to not have the outer helmet that it currently has, so i thought that it would be good to use the bandets head and redo the blp for it. i also need the lights removed from his back and the boxes on his wast and back also removed. and if at all possiable, the gun sound removed as well. this mdx will be reskined to resemble samus from metroid. would have liked to attach a cannon to one of his arms and changed the attack animation but that may be too hard for a request.
p.s. there needs to be more mods done to the marine for this sight any of thiese modifications would help unless they leave large holes in the model :?
