Been looking slowly through Special Modifications (hence all the posts today. sorry!) and noticed there are a lot of a things you /can't/ do with the item/weapon crafting. Now, I know it will be between me and my gm, but I was wondering what your thoughts were on allowing the use of an existing item to be used as step 1 and 2 for your template and resources. So instead of picking say the energy pistol template for 200 you buy the precision pistol for 1k, spend your 12 hours at 3p difficulty and get (die roller don't fail me now) 1 hit and 1 triumph net at my current 2y2g. So I successfully constructed (customized/upgraded) the pistol at its book stats but use the triumph to reduce the crit rating from 4 to 3 with that particular roll.
I figure in the long run you could get some pretty exotic weaponry but at much higher cost than a 100% custom job. Do you think this would get too out of hand for your game or add a little extra customization during down times beyond just slapping an attachment on the weapon?
