I don't think this is possible from Perl code right now.  You need to
call CreateFileW() to open a file with a Unicode name.  If you want to
hack something, then I would suggest to write a little XS module that
just swaps out the file handle in a PerlIO* structure.  Look at
PerlIOWin32_open() in win32/win32io.c to see how Perl currently opens
a file.

Another quick-and-dirty "solution" would be to build a custom Perl
by hacking win32/win32.h.  If you change the USING_WIDE definition
to "1" then you end up with a version of Perl that has the old "-C"
behavior hardcoded.  Remember that this is not really compatible with
Perl's Unicode handling.
