Object merge - Is it possible to merge dependencies?

Hi All,

I imported a huge count of data objects of one class. Now I see that there are several data object items which are of same class but in some way duplicates of each other. I would like to merge them, but I need a good solution for the dependencies tab because these objects are related somewhere else in 25-30 places as M:N or M:M Relation. Is there a possibility to merge the dependencies?

Object A - 20 Dependencies
Object B - 30 Dependencies

Result Merge:
Object AB - 50 Dependencies

Thank you for any hint

Kind regards,
