Check out this link for some samples... (remember that negs can be corrected to alter the bias of the film...)

When I worked at a lab, we had some customers that routinely cross processed film with different results. Agfa pro films came out with green casts.

One customer shot a Kodak amateur slide film (Elite 2 100) that cross processed so cleanly it was spectacular. It was grainy, snappy, but the colours were in the normal ballpark. It was great for portraits, which I believe you do most... Hope that gets you closer to your goal,
