There isn't any way to "double up" a rotation sensor. It needs to be connected
100% of the time to prevent it from missing counts.

I'm not sure that's accurate. Let's assume a 8-bit rotation sensor. The
first question is "Do we really need 256 discrete rotation positions?". If
there isn't a good reason then the LSB becomes available. If you don't need
128 positions then the 2nd to LSB becomes available. etc.

| (...) connected (...) Let's assume it is the LEGO rotation sensor. Which is not an 8-bit sensor. It is an incremental encoder that sends values back as 4 analog values. If a touch sensor is put in parallel with a rotation sensor the analog values (...) (25 years ago, 28-Apr-99, to lugnet.robotics)
