Unless you add a bit of electronics to multiplex your sensors, use the
existing three digital inputs as a mini parallel port, design a simple
communications protocol and send the sensor statuses from the module to
the RCX using the protocol.
A bit excessive for most things I agree but you should be able to design
it so that it supports an arbitrary number of sensors and it could even
support analogue sensors if the interface module had an A/D converter
and the communications protocol supported the transfer of n bit samples!
