It depends, you know. Anyway, I (or someone) would need to create a merging tool. In the case if data structures will change it will be hard to move your changes on a new version. Same story about situation, when you cloned too much new objects with 6-number length guids. They should have overlap with new ones.
Ok I will continue testing.
For now you helped me very much.
thanks again for creating and sharing this tool. I appreciate it and your work!
