It's always helpful to make the distinction between problems and solutions; it's true that traditional finance providers are horribly stuck in legacy systems, however their main problem is not so much that they are unable to rebuild. Their main problem is that decision power is so federated across the organization that it's impossible to even decide to rebuild their stack in a vertically-integrated way. The only way an organization can revamp this is by actually owning the technology entirely in-house and building up a completely independent product and engineering division. At the end of the day, changing code is orders of magnitude cheaper than a change management project with 12 managers and mandated retraining of 400 internal personnel. In my humble opinion, this type of change in the financial services industry can not come from incumbents.
