IANAL, but I doubt FDIC vs SIPC matters for an average consumer. If either fails it would almost certainly cause a major run on banks and/or a systemic money transfers failure. Thus it is much cheaper for the gov't to print more money than suffer such consequences.

And if the gov't really wanted to weasel out of FDIC there are plenty of loopholes. For example, I think FDIC can take a long time (up to 10 years?) to pay and is not adjusted for inflation, so inflate, wait and pay pre-inflate amounts is an option (stupid, but technically possible).
