For final info I'd contact Kodak @ 800.242.2424x60. However, I've cross
processed since 1966 on E-4 through E-6 and never had a single problem.
Problems arise with careless times/temps/agitation. ALWAYS though, I have
kept the films separate when doing so. Since you are on a line and it is
constantly replenished I do not think you'd find any overall changes.
An interesting one to try is Kodak's Infra-Red color. It needs an E-$
process but you can do it in E-6 w/a lowered temp and extended times.
Makes a great print of strange colors on standard chromagenic papers.
