I am in the process of considering a TL in which Valens won the Gothic War (https://www.alternatehistory.com/forum/threads/alternate-adrianople-aftermath.416978/) and I am entertaining the idea of a WRE that lasts a few centuries longer than IOTL and eventually fragments into a cluster of Latin successor states. Is this at all possible, and if so, how would such a situation come about?
