I know that this sounds somewhat unorthodox, but what about using NM-B inside the conduit?

Since you are going to be alternating fixtures, you could pull the cable _through_ every other junction box, and never have conductors from different systems exposed in the same junction box. This would seem to eliminate the problem of accidentally mixing conductors from different panels.
