This idea, probably first articulated more than two decades ago
at EuroTeX (Arnhem), 1995, could be used in an etex-capable engine
using etex's \savinghyphcodes:
\begingroup \savinghyphcodes1
\lccode`\é=`\e % setting the equivalence table using \lccode,
               % mapping `\é to canonical character `\e
% input hyphenation patterns
I doubt it works in xetex with more than 256 character
equivalence classes needed for full Unicode, though.
But it could be used for any set of languages/dialects 
with less than 256 characters/classes used in hyphenated words.
