Well it looks like the hourly Rugeley Trent Valley to Birmingham International via New Street terminates at Birmingham International xx55 and then forms the xx18 Birmingham Intl. to Liverpool. That's how it looks to me on real-time trains and from what I can gather from journey planners anyway.
And it's that complex interworking pattern that I believe will be the house of cards, not simple splits/joins. If you keep it self contained, then if it all goes to hell in a handcart you can cancel a couple of services and get everything back in the right place to restart on time.
