In Mem, languages and scripts set default encondings (with
\SetScriptEncodings), but it never sets the font family,
except, as you said, if explicitly given in the document
in \scriptproperties or \languageproperties. So, if the current
encoding is T1 and the family is cmr, and we switch to, say,
Greek, then Mem shall see if there exists LGR+cmr (this part
is not yet implemented in full, but the basics are already
there). Very likely, LaTeX3 shall work more or less in the
same way.

And European -- don't forget Spanish (Latin and Hebrew scripts).
