the ability to convert to a Non-O visa inside the country has been around for a long time. The banks have recently got a lot stricter on who can open a bank account. Are you saying immigration should stop offering this service just because YOU are having difficulty opening a bank account?
its all perfectly logical. It is possible to open a bank account on any visa or no visa at all, its just very difficult. If your wife has a bank account start with that bank branch, if she doesn't find another thai of sufficient standing to vouch for you and get a residence certificate from immigration before you go. You might need to try many branches of many banks though
