There are known reasons for why most people with CF become pancreatic-insufficient. It is not something that is still left up in the air as far as guessing why the process occurs (i.e. is it genetic? Is it a process of deterioration?) It is part of the disease process of CF.
Not everyone with CF needs enzymes- a fortunate minority are still pancreatic-sufficient and don't- and there are other factors that can contribute when people with CF have trouble gaining/maintaining their weight, outside of pancreatic function. (For example, those with CF need substantially more calories than someone without CF of the same age/height to maintain their weight.) There are supportive things that we can do that can improve the digestive process in some cases for some people... but I wanted to point out that it's not still 'theoretic' as far as why pancreatic insufficiency occurs in the first place.
And given the progressive nature of the disease, without a way to address damage already done to the pancreas, I would not be too optimistic about this at this point of CF treatment, once one has reached the point of needing enzymes. I am not saying it's impossible- only your dr could tell you that- but I don't think it's common.
