hmm..When I got in, before I talked to the guy, I dropped several of my crucial items on the ground, and picked them up right after the dialog. The non-crucial stuff, I just let him take since it gets stashed away and is returned later.
hehe..I thought of something like this when I first noticed the "Adamantium Skeleton" perk. Probably wouldn't be tough. Seems like a fairly simple model to make. Though I don't know it would look as good coming out of bare hands. Perhaps fingerless gloves? Might be kind of cool to make an all-around Wolverine or Lady Deathstrike type character. Maybe a bit of a regeneration effect, and a few animations if people are up to making them. It would be amazing to charge an Enclave Soldier, ram your claws through his abdomen/armour, and throw him in the drink.
