I’m still deeply intrigued by Cameron’s theory of the opened portside gangway doors which could cause the ingress of water from that side (in addition to iceberg damage) and the growing list to port, accordingly…

Whether the forward E-deck doors or the D-deck doors were open or not doesn't matter much. By the time the water reaches those doors, the interior is already flooded. New water entering there is not under presure, it just flows in like a lazy stream or barely at all. The water at the lower openings is still forced in under pressure so the doors and other openings at surface level don't really effect the timeline for sinking much.
Water under pressure from a smaller hole will fill the ship faster than larger holes under no pressure.
The trouble starts when the ship's damage stability goes negative and ship no longer wants to float upright. That happened about 2am. The ship suddenly starts to tip up or roll over MUCH faster. Titanic tipped up. By then, lots of openings were submerged so, again, it didn't make much difference.
