Again, just my thoughts and comments:
The dimensions of your tank are going to be visually stunning! BUT, it is going to be very difficult to aquascape that to allow the fish to create and maintain territories. If the tank were something like 120"x30"x30" you would have ALOT more stocking potential, and your list just might work - but in those dimensions - it is in my opinion dodgy......
If I were stocking it, I would be inclined to view it from a territory, not a biological load point of view. While your tank allows alot of scope for the latter, it really doesn't allow all that much more than say a standard 180 (6x2x2) - in my view. Now if you were talking a reef tank, with lots of little fish like grammas and chromis and gobies and so on, you would be able to create a large reef wall, and provide for territory that way..... but if you do that with big fish you are going to push them all into the centre, where trouble is bound to break out.
I'm not trying to tell you what to do here, just giving you my opinion on what I would do if it were my tank - I would omit the following:
3x Pyramid Butterfly - Yellow
1x Parrotfish - Princess
1x Clown Tang
1x Pennant Fairy Wrasse
1x Lunare Wrasse
I say this on the basis that you are not going to be able to provide secluded areas from them to stay out of the way of the "big boys" and if forced to compete directly for food space I do not think they will last that long. I would add that my suggestion to remove these does not follow on to say add something else to the list. You'd still have half a dozen LARGE MEAN AGGRESSIVE fish in that space, and another 4 or 5 medium bodied...... that is still alot in my view, and in a few years time you'll end up having to review your stocking levels.
Just to reiterate - this is just what I WOULD DO........
And the tank is still going to look spectacular.......
