Thinking about this kind of thing always drives me crazy during layout. One thing to consider is the angle of the knot as it passes through the rest of the stave. If it angles in, for example, you might not be able to get past it all the way down to the belly. If you go to the inside, I wouldn't worry too much about following the curve of the wiggly side on the other - just follow the grain on both. It looks like directly transferring the curves would cut through the grain on the RH side.
