I find it interesting, though if I go this route I'll probably try to find some Vision3 and proper developer and do it myself. However, my skill-level has to increase before I attempt it.
For me, the color shifts would not be as important as longevity. I'd expect color "issues" from cross-processing, but would want the images, however they turned out, to last. That is probably why I've not yet tried cross-processing, as fun as it sounds to me. I have some terrible, grainy, ill-lit, half-blurred photos I took in my childhood when I was first learning to use a camera. They have lasted, so I still have those memories.
