Snowflake Royal I think the idea that Ilori and Moore don't compliment each other's game and are too similar to be effective together has a lot of merit. Nothing wrong with not being a physical beast (Ingimarsson anyone?) But we do miss a bruiser.
I think Ilori in particular needs someone experienced and solid next to him as his worst games tended to be when paired with Blackett, who I think Moore would do better with.
Pearce, for all his faults, would be perfect alongside Moore or Ilori.
Ingimarsson had Sonko with him. So yes, a classic defensive partnership (Eg Bruce Pallister) one putsbthe head in the other clears up.
Although according to Kitson ingimarsson was a hard bastard who could definitely look after himself. (As was Gunnarsson)
