Sure, it's possible, that doesn't mean RPL is going to do it. Doing so requires having somewhere in the packet to store the original value, which necessitates a header; if there's a header, there's no point in changing the flow label. It's my understanding there are some proposals out there for doing this, but in other domains -- this was mentioned at the mike in Hiroshima -- but that by no means indicates RPL will.
