No, the solution that will be implemented is likely to be write-from-scratch. Ultimately, you can start a new bank with new technology, move clients money to new technology, have the old bank go belly-up and bankrupt. Sometimes that happens in a new company, sometimes it happens in the same company (i.e. re-writes). Maybe not so extreme, but I think that's likely what will happen over time. Maintaining old software is a choice, and is sometime more expensive than it's worth (depending on what that software does). It can certainly be very painful in certain cases (the Great Depression was a similar "reset" for the financial system as a whole - though without code involved), but the market mechanism will accomplish the objective, though likely not without collateral damage.
