No, I don't think so.  The display engine's interaction with the 
non-ASCII characters support is mainly in two areas:

  - it uses various functions and macros to walk the buffer one character 
    at a time (since Emacs uses variable-length encoding of characters);

  - it maps characters to font codepoints

I think the latter doesn't have to change radically for Unicode.  As for 
the former, those functions and macros are not specific to the display 
engine, and need to be rewritten for Unicode anyway.
