I think they are just instruments. If modding them is what you want to do, then do it. However, 99.9999999999% the original or replacement Alembic components are going to be a superior option. Don't forget that Alembic started as the original modders. What makes modding not such a great option is that few modders can do work that surpasses their standards. Simply tossing in some EMGs hardly seems worth it, but someone comes up with some radically different idea that produces some cool results, who's to say?
