The big problem, for me, with trying to squeeze random RP in the middle of an arc is that the arc usually takes far longer to play than it's supposed to take for C'kayah to live. Something that might be 3 days for C'kayah could take weeks to play. This creates a continuity problem that makes it hard to do other stuff during the arc.
What I've ended up doing is pinning the end of the RP arc to the day we finish it, and then tracing back, instead of pinning the start of the arc to the day we start. There are still continuity problems (i.e.: it's hard to reference the arc to other people in RP before it's done), but it makes it far easier to work other RP into it. Those 3 days don't actually start until 3 days before the day we finish them, so there's no reason for C'kayah to be unavailable during the weeks we're playing the arc.
