Do not change the order of the names on your tax return. Changing the order of the names on your tax return will do nothing to help your spouse get SS or Medicare. There are rules for SS that determine that--and where her name is on a Form 1040 is not one of them.
Changing the order of your names when you have been filing a joint return will confuse the IRS and mess up your tax return. When you transfer the 2022 tax file to 2023, a lot of information comes over ----changing the names does not change where that information was and where it will go for 2023.
