16 months is a long time, especially when people are in jail and they should not be there. However in my experience as software developer nothing is simple, but everything can be done.
First problem coming to my mind: do they have the budget to pay the software developers to add this new functionality to the software? Do they have to ask the money to someone else, maybe to the very politicians that changed the requirement?
Then when this is settled there are the usual problems of analysis and implementation. Probably also where to get that input that they didn't have before. It could be a large project. But 16 months, ouch.
