In general, such an approach might cause troubles because of 
inter-library dependencies.

Without any knowledge about the implementation of Boost.Filesystem, 
I can tell you that there is another way which is at least as 
effective and at least as easy. Keep your 1.46 installation as it 
is. Install the complete 1.40 tree in another directoy and build 
it with the option --with-libraries=filesystem set. This may 
overwrite your additional copy of the 1.46 headers in some 
system-wide directory like /usr/local/include; in that case, just 
re-copy it from $BOOST_1_46/boost. Alternatively, you can use 
custom target directory settings from the bootstrap script (refer 
to bootstrap --help for more information).

Then, for all Boost libraries except Filesystem just keep using 
version 1.46. For the Filesystem library, include from 
$BOOST_1_40/boost and link to the library that you built when 
installing version 1.40.

HTH,
