The big transaction networks are so heavily invested in their own system and the effort to integrate is such that the likelihood seems quite low. Had the foundations of bitcoin had as a primary goal industry transition to using it, it would have become a stronger disruptive force. Upfront integration costs are on the scale of concretely-estimable billions with the any long-term rewards ambiguously-estimable. The certainty is that is divests control and related control of the transaction network. Where's the value to the existing network that reaps the transaction fees?

It made some inroads, but a future alt-currency alliance would need to find very forward thinking technical leadership from within the entrenched industry willing to put their names into efforts of such an alt-currency alliance. Those players would need buy-in from the business and political wings of their organization. Where are the CEOs at banks and transaction network players who feel moving to a non-sovereign currency makes bottom-line sense?

Finding such value and leaders seems unlikely due to political relationships that the entrenched financial industry has. Put your name on an effort to remove oversight and control of the nations whose central banks you presently need at your own risk.

Unless the banking industry gets burned like the tech industry has in terms of the Snowden revelations and popular movement around privacy, there isn't an obvious self-interested basis for taking on this sort of risk.
