Just wondering: I've cross-processed colour film both ways (c41 in e6 and e6 in c41). I know it has its quirks (like with regards to ei-rating) but it gives nice results sometimes (after lots of experimentation).
Is there any way to cross-process paper? Or is all the positive-paper chemistry gone too? (or does colour paper just not work this way? I too have unfortunately never had the pleasure of using Cibachrome)
