Movement, electric impulses, nerves, are observable/measurable stuff. I'm not sure that your example is analogous to qualia. You suppose that qualia is material. It may be, still I find it very hard to imagine how it could be. What is our subjective experience made of? How electricity and neurotransmitters cause subjective experience? It appears that there's a gap between objects and qualia because only I can see my qualia, while everybody can see a brain or measure electric impulses.

Anyway, I like your hypothesis that it could be answered by science. It can lead to interesting experiments and theories.
