Would \savinghyphcodes help? According to the documentation of e-TeX, setting this parameter to a positive value would save the \lccode values in effect during the execution of \patterns and e-TeX (so also XeTeX and LuaTeX) would use those "frozen" values for hyphenation purposes. This would avoid the need of changing the \lccode of any character as part of babel or polyglossia modules, Setting \lccode"2019=`\' and \lccode`\'=`\' when French or Italian patterns are read in should also avoid the need of pattern duplication. It is a problem also for Catalan and some other languages, Of course this can't be used in regular knuthian TeX, but it shouldn't be an issue, since we are discussing about Unicode input.
