This is possible as I am trying, my first proc will come on 4th try no matter how many times I reload my game so that's definitely not random but already decided.
EDIT: Ok I have figured it out now and I will try to explain as better as I can so if anybody else is wondering can get some understanding how this works.
The proc chance which is listed on the item is real but its calculated when you obtain the item or when it actually procs next when you craft an item.
So lets assume you loot Bear claw's which have a 30% chance of producing 10% better equipment, as soon as you loot them their chance of proc will be calculated and saved by the game. Lets assume the dice roll decides it will proc on 3rd attempt so you will have to craft weapon/armor with bear claws atleast 3 times before it procs, saving and reloading won't help.
So once the proc happens the game will immediately roll again in order to determine the next proc and save it again, now if you save your game at this point then your proc chance is saved with it, the dice isn't actually rolled when you craft the item but when you obtain them or gets a proc to happen.
I guess this is bioware's way of disencouraging people from craft an item and if it doesn't proc then reload and try again because then the chance of critical crafting success wouldn't really matter.
