Honestly I cannot see the advantage of making it all fit with each other. Even in the DM Guide they offer different world philosophies, e.g. Heaven Hell Prime (shadow) for something very basic,
Great wheel, Axis etc.
The only time you really need something logic is when you are doing the following:
1. And precondition: You are a DM who sticks to the published material (mostly) true to the letter, especially on things like canon
2. You decide to connect two or more official primes (Or planescape) in a campaign.
For every other scenario NOTHING has to be done, Eberron works fine with its own philosophy of the planes (Better eventually than with some shoehorned great wheel), Dragonlance works well with its Philosophy and any of the primes of the official settings are far easier to shoehorn into a homebrew plane arrangement - aka axis instead of wheel - than to be implemented into the planescape universe which is a great setting, but on its own, and not as an INTERPLANAR SUBWAY of some sort.
Btw [MENTION=22779]Hussar[/MENTION] help me out here, I am not at home and cannot look it up: Tiamat / Takishis was put into one of the nine hells layers as far as I can remember, ?whereas in Dragonlance 1e she was from the abyss? I think they also did change her alignment from CE to LE at some point for that? Am I correct?
