Having recently been enlightened as to the incompetence of record labels when it comes to handling revenue splits in the simple model (e.g. they can't even get them right for Tier 1 artists with a simple split between authors), I'd not hold out much hope they'd be able to cope with a more complex model like this. And that's before you get to antiquated places like the PRS who would also need to be involved.
