Thanks
blssdwlf for the graphic visualization.
Although not illustrated, I'm confident that the relocated-towards-the-stern intermix shaft would also fit nicely into the 1000' / 305m version.
Additionally, it could explain why the "back wall " of the torpedo bay is slightly bent inwards (to make space for the still vertical intermix shaft behind).
And the "photon exhaust" at the stern of the connecting dorsal could serve as a heat dissipator for the shaft.
This would also facilitate the accomodation of the vertical turbo shaft according to the
turbo lift car schematic. Upon closer inspection I noticed that the turbo shafts in the engineering hull "list" towards the port side. Amazing! So the off center blue corridor ahead of the engine room seems to have been aligned off-center-axis on purpose to create the necessary turbo shaft space.
While it's nice to see that the set designers probably payed attention to these details, it incredibly sucks how they ignored Andrew Probert's layout.
VERY colorful! What's up with the hump at the stern of the nacelle?
Regarding the mysterious 3rd and 4th torpedo bays, its probably time to dust of this old article on the subject:
http://www.trekplace.com/article01.html

I reread the article prior to posting. While you could probably squeeze in a starboard torpedo bay # 2 (without the loading mechanism which would have to be closer to the port side and off the center axis), there's no way you'd have additional torpedo bays 3 and 4 at this location (unless these were somehow compartments that revolve like a centrifuge near this area).
I slept the night over it and here is my proposal for rationalization: These panels (1, 2, 3 and 4) are actually loading indicators of some kind. When Kirk and company enter the ship torpedo # 1 is in the starboard, torpedo # 2 in the port firing tube. Just prior to the Mutara battle, they had additionally loaded torpedo # 3 and we seem them loading torpedo # 4 into the [port] tube (thus, the Enterprise has four torpedos prepped for the encounter with the
Reliant).
Fact is that
after the torpedo bay (and its loading mechanism) had been rendered inoperational,
Enterprise fired two torpedos from the starboard launcher,
first one two destroy the Reliant's launcher pod,
second to destroy the port side nacelle. Therefore, these torpedos already had to be inside the launching tubes!
Good news coming from that would be that we have a much better chronological system for the docking ports (and airlocks):
- Docking Port and Airlock 1 - engineering hull starboard side
- Docking Port 2 (only!) - torpedo bay starboard side
- Docking Port 3 (only) - command bridge
- Docking Port and Airlock 4 - torpedo bay port side (apparently there is no airlock on the starboard side, because there is only one airlock control panel on the port side in TWOK)
- Docking Port 5 (only) - engineering hull port side (as seen in TMP)
- Docking Port (and Airlock?) 6 - starboard underside saucer
- Docking Port and Airlock 7 - port underside saucer (as seen in TMP).
(The
Official TMP Blueprints clearly indicate these two hatches at the saucer's underside as "docking port - saucer")
Assuming we take the TMP recyled shot ("Docking Port 5") in TWOK serious (as suggested by
blssdwlf), the docking port numbers could have changed into something like this by the time of TWOK: 1 - bridge / 2 - starboard saucer / 3 - port saucer / 4 - starboard torpedo bay /
5 - port torpedo bay / 6 - starboard engineering hull / 7 - port engineering hull
Anyway, as a practical result we'd have two airlocks on each side of the ship, one at the engineering hull and one at the saucer.
However, assuming that the torpedo loading crane would be on the center axis of the ship, the size of the set would suggest that we are looking at an Enterprise not larger than 1000' or 305m, IMHO.

P.S.
I think there is a possible explanation where the docking port confusion in TMP (travel pod docked at DP 5, intercom however says DP 6) might come from. Earlier on the orbital complex we saw an "interior" DP 6 behind Scotty. However, the travel pod departed from "exterior" DP 5 (same set of doors like the one used for the
Enterprise). Somebody may not have noticed that for the "interior" of the Enterprise they changed the "interior" orbital complex from a "6" to a "5" to match the exterior door. Possible someone expected they did it the other way round (i.e. change the writing on the exterior door from "5" to "6").
