That said, if you want to avoid the car shuffle you could do this as a return walk from Wog Wog, with some variations on the return to avoid repetition, in 3 days. The only part you would miss is the trudge along the base of the Castle to Kalianna ridge. This would involve camping both nights at either Mt. Cole (in the caves) and/or Bibbenluke and a long second day out to the Castle and back... if you have enough daylight on that day you could return the "back way" between Cole and Owen. Similarly if you had enough daylight you could go via Corang Cascades area on either the first day in or last day out to mix things up (as opposed to Corang Peak/arch in the opposite direction). All doable but 3 pretty long days (or 4 more leisurely ones).
Alternatively if it's quicker/easier to drive to/from Yadboro you could go in via the Castle to Mt. Cole, visit the Corang area as a daytrip on the second day and then out via Owen, or variations on that.
Haven't done Yadboro River/Snedden Pass but it's reputedly a bit of a slog and at a guess pretty tough in a day.
