That solution always pulls the `,' from math mode, so it comes from
the same (roman) font, even if the current font is sans serif or
whatever.

yes, you just go \fontsize{something}{0pt}\selectfont. The question is
what value to put for `something'. The suggestion below (\commaB) uses
the value \ssf@size which is the internal comand NFSS uses to store
the scriptscriptfont size for the current font. This value is not
initialised until the first time math mode is used at a current size,
so there is an empty math list first.

Apart from the change in font the code is identical to the original,
which centers the comma under the letter, I can not judge whether that
is a good position, not knowing Romanian...

As J"org mentioned in his reply, any such constructions will break
hyphenation. To get hyphenation correct then you need to construct
a (real or virtual) font.
