An active multiplexor would solve your problem. Take a look at the one sold at www.mindsensors.com, it allows you to hook three sensors to one input port. The sensors can be of any type. They don't work directly with legOS, but I've summited a legOS (...) (23 years ago, 11-Mar-02, to lugnet.robotics)
