No, for mkii you should look at math-*.mkii files. The relevant file in
this case is math-tex.mkii, which defines

\definemathsymbol [ldotp] [punct] [mi] ["3A]

You need to define a new math encoding (see math-ams.mkii or
math-eul.mkii).

\definemathsymbol [ldots] [inner] [mi] ["XX]

where XX is the location of the glyph.
