Here in Australia there is a team building a new bank and having good success doing so. In order to overcome the institutional barriers like the one the OP raised, the team consists both of highly experienced corporate "grey hairs" and talented young hackers/designers.
This way, they have the industry experience and network to ensure the company is run competently and prudently, whilst also being able to leverage the energy and creativity of younger hacker-types who can bring new ideas to the market.
I'd suggest to the OP that this kind of approach may work for them.
