Hi Timothy,
1. The VLS mounts port and starboard of the 20" Guns Were intended for ESSM use while the guns were un employed
That's a lot of missiles, and the majority of your VLS space. My other concern about placement there is blast protection. Anyway, your ship.
2. The vast aray of goalkeepers and Searams are to enable the ship to do one-on -ne with a carrier and it's airwing plus any cruiser missile the battle group might decide to launch at the same time a la the WWII Japanese Kamikaze attacks.
Well, I'd honestly prefer to have something larger than the Goalkeeper to start engaging at further range - a 57mm mount is what I'd prefer for CIWS going forward.
3. Good point but while designing I reckoned that the dual purpose role of the goalkeeper could fend off light boat attacks. (30mm is the smallest round to have a boost chage-- I believe.
I'd go with the full 21 round RAM launchers in place of SeaRAM if only to also have enough space for more RAMs, which also have surface mode, or even Javelins (which can fit in the Mk 49 launcher). The performance difference between having and not having on-mount cueing is going to be marginal, and the extra rounds will be much more helpful than the extra radars.
4. Oh yes. The radars. I was trying to use the upcoming spy-3 and Missile Defense Radars (AMDR) , Both of which I can only guess at what they might look like so I made them pretty. I know, no excuse, but that is what I did.
Ah, I was initially refering to the hodge-podge of directors that you are mounting (SPG-62s and SPG-55s). If you need a lot of gun-laying radars, I'd suggest replacing most of those with SPG-60s, or something similar. I'd also look into designing a phased array director - you can hand-wave it as an outgrowth of TPY-2 (the THAAD radar)
As for the radars you wished to use,
This Burke Flight 3 has the AMDR, while
this USN miscellaneous electronics sheet has the SPY-3 radars and the VSR. I would also consider moving toward a totally enclosed and phased-array solution.
Edit:
Also, we have a top-view of the V-22, and the side-view of the real V-22 AEW proposals:
