There is no way to convert the Management SmartObject (SmO) to a 'Packageable' SmartObject; you must remap the controls with a new SmartObject.
The best method is to create a copy of the Management SmartObjects in Designer. This will ensure that you still have all the functionality from the Management SmartObject but the copy will not have a system binding. While in Designer, navigate to the Management SmartObjects and left-click on a SmartObject. You will click on 'Save As' and then you can give it a new name and save it to a different category. Once you have a copy of the SmartObject, you will replace the old SmartObject in the forms and views with the new copy SmartObject. This can be a tedious process but once completed we will be able to Package and Deploy the solution without an issue.
