So far, the two known life links were formed between a Murakumo and an Azure Grimoire (Nu - Ragna and Mu - Hazama). Seeing how useful it is and that there are only two known instances of it being made, it's probably not a simple thing to do. Not to mention that Terumi and Hazama aren't the same person.
