Theoretically, could one just make a pack of unrelated adults by taking mates then dying?

So in the past year in my current file I kind of pulled a quick swap in leaders but didn’t want to screw my numbers over so I had my player wolf, we’ll call her Fwolf, find a mate I’ll call Mwolf. I then had Fwolf die, and gave the pack to a grown subordinate. Mwolf became a subordinate and is still in the pack for now.

This got me thinking, if I kept killing my played wolf (related subordinates from previous years I.e siblings or pups) getting them mates, then killing them and inheriting the pack as a different subordinate, repeating the process, would I be able to assemble a pack of random unrelated dispersals? Obviously this requires some setup (having a bunch of grown children to be able to swap to as player wolf) but I think it would be interesting.
