Complicated geomerge/anim transfer request

[Punisher]

get rid of the barrel of marines rifle and add the spinning part plus barrels of domokuns sentry gun onto the rest of the marines gun but a little lower and add the spinning barrel animation to the marines attack animation so that it looks like the marine has a chaingun. Heres a link to the model http://www.wc3sear.ch/index.php?p=Models&ID=1566&sid=2bf30c10d988baac9c73ce07b88e813a
