Just replacing the binary will certainly break your TeX Live system.
In order to experiment with the new binary, it's best to create a
cloned TeX Live:

  cd /usr/local/texlive
  cp -dpR 2012 2012-test

If other users have access to your system, the following steps are
advisable too (reason explained below):

  chown -R <user>:<group> 2012-test
  chmod -R go-r

Then replace the LuaTeX binary in


and re-create the format files.

MacTeX allows you to switch between different versions of TL.  But I
don't have a Mac and hence don't know whether the new version is
recognized automatically.

On Linux you can switch to the cloned TL temporarily using a shell
script, say TL2012-test.sh:





exec /bin/bash

On Windows it's quite similar to Unix but environment variables are
global by default.  You have to use setlocal in your batch file,
otherwise you don't get back to the official TeX Live when you type
exit in the current shell.

As Herbert already pointed out, it's necessary to modify packages in
order to make things work.  Before you do so, please study the package
licenses carefully.  LPPL allows you to distribute modified files
under certain conditions, but it's undesirably though.  Therfore the
instructions above to make the cloned TL unreadable to other users.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
