You need to have packet numbers or other such identifiers so that you know when UDP packets have disappeared, duplicated, or changed order, anyway, right? So you can use those packet numbers as part of the IV.
If you think you need the "self-synchronizing" feature of a cipher mode then you're doing it wrong. I recommend the book "Practical Cryptography" by Ferguson, Schneier, Kohno.
