Hm. I do have a bit the impression as if we have here a context and
latex philosophy clash. I'm not asking you to provide a funktion
incorporated in the context code which does the job. _I_ want to
write support files for the chess ttf-fonts. If I get something
working I will perhaps add it to my package. And if something
changes in luatex or the underlying luaotfload/context code, well
then I will have to adjust my code.  

Couldn't you give some examples how to manipulate a font after it
has been defined with \font\test (if it is possible) and then let me
play around?
