This is probably the right mailing list, however:

(a) There is currently no working-out-of-the-box solution for that yet.
(b) Making it work for yourself only must be reasonably easy to
implement for somebody knowledgeable with LuaTeX (see loadlanguage in
tex/luatex/hyph-utf8/luatex-hyphen.lua).
(c) Making a systematic approach and enabling this on the package
level would require either modification of polyglossia (once
polyglossia starts supporting luatex) or some modifications of babel
or maybe the files under tex/luatex/hyph-utf8. But I'm not the author
of those files and it would help if Manuel (author) or anyone else
would jump in. I'm not even sure what the (babel) syntax should be.

Were you looking for (b) or (c)?
