That depends on how much the applications rely on the data.  The
above-mentioned LD_PRELOAD library is an option (although documenting
it in an effective way might be a challenge).

If the applications expect 32-bit ino_t values to uniquely identify a
file, we can't solve that without a rebuild (... or keeping a
persistent database mapping "real" inode numbers to a 32-bit
namespace).
