To be honest all of the idents could work just for ITV1 and if they had 20+ variants it would actually be a decent enough set.

There is no reason why those ITV3 variants couldn't work on ITV1 for dramas, ITV2 variants for entertainment etc. There's just that weird aliens one from ITV4 that should probably not make it. But they could all just be idents for ITV1.

I would give the entire set to ITV1 and ditch the cross-channel concept and let 2,3,4 & Be go back to being something more distinctive.
