Yes, above idea is best bet. The IR beam from the handheld-remote is fairly directional. The receivers are omnidirectional (symmetrical red lens on top). If you operate from roughly the same position you can shield or mask the receiver lens to only "see" the line-of-sight IR beam coming from the remote rather than reflections off walls, ceiling, etc.
