You did ask a question on a board of people with varying interests and knowledge. This is just a recap of some of the obstacles you are faced with. Hoping for ratification on a highly speculative venture isn't what you will find here. Storing guns or using them has no bearing on how a gun functions when it is used. It isn't impossible to get a bolt and fit it to where the gun will shoot, but it is similar to having a mirror, then trying to fit a truck to it. Sure it can be done, but time and money should determine what any gun is worth and I think you are blinded somewhat by having that action and what the end result will or could be.
