I'd try the LD_PRELOAD trick before going for a chroot solution. (Disclaimer: I'm not sure how to do the chroot thing, maybe someone else on the list can tell you about it). See <nixpkgs>/pkgs/applications/audio/spotify/* for an example of how to use LD_PRELOAD to dynamically rewrite paths for a binary-only program.
