Honestly, it would make perfect sense. After all, the completed Hōgyoku seems to be in some way related to the SK; it can transcend beings to the SK's level and it can turn humans into Fullbringers just like how SK fragments can. Hell, Yhwach's ability to give Schrift to Quincy also seems to be suspiciously similar to that.
