Personally, I think you could make a case for dropping all of Three, Four and CBBC as linear channels and using the 'spare' space from CBeebies as a BBC Extra channel for sport/live music, with a mix of archive and/or iPlayer highlights otherwise. As I said the other day, when taking into account cuts, reductions in content and changing viewer habits, it'd be better to consolidate and have two stronger main linear channels, than a handful of more fragmented channels that are mainly repeat-based. There is enough space for the content still produced by those channels to be given linear broadcasts, while gaining the savings from reduced distribution, infrastructure and support costs.

That's not a bad idea at all - though I think you could probably get away with keeping the BBC Four name. There's always been a lot of music on BBC Four, after all, and over the past few years even sport. I think it's right that what has traditionally been Three and Four content moves back to BBC Two, a channel which has really lost its identity over the past 20 years.
