I've always disliked the real T43, not just the odd centre flightdeck but the whole odd layercake looks and missiles and radars sprinkled all over it, if anyone drew something similar we'd laugh it off as a terrible kitbash! I felt a high value ship should have some RCS and since Types 23/24/25 and 43 overlapped in time to some degree it felt right to explore the aesthetic. This ship owes something to your Super T23 designs too.
The directors probably are offset, I think there is enough room. I had toyed with fitting 4x AESA but I felt the different fire-control methods for Sea Dart and Active Sea Dart would prevent that so I stuck with the mix of directors. I had doubts about having 32x Sea Wolves so high in the ship, I think it would work ok on the beam but that's the beauty of 2-D drawings, I can remove the portside launchers without having to change the drawing! I thought of a midships block on each beam but it would interfere with the uptakes and downtakes.
I'd wonder about perhaps swapping the directors around and raising the 912s to super-fire the 909s as it were. You'd need to raise the nav radar (and possible make the mast taller as a result) but it would allow you to keep everything on the centreline.
Personally I think that 16 VL-SW would seem more plausible, at least above decks. Ideally I'd have looked at the using the Vickers auto-loading launcher amidships but rocket efflux would most likely be problematic to the intakes.
