I took some time, And drew up all my ideas on one image.

Yes, that a lot of changes, but bast needs work, and I put down everything I thought might help.
The weldable, (Bast needs some) open this way.
The one in bridge allows the door at ms to be opened.
The one near the wall hiding the node allows marines to access the node, aliens should have a vent that lets them in to the node.
2 nodes are moved in my plan, and there is 3 possible new nodes. The first, is hidden behind a weld point, the second is in bridge to make that area worthwhile, and third is in the new room that uses to be the left half of refinery. The map should have a seige point in the hallway beween the two rooms, but only in there.
I planed out a lot possible vents, Bast need more vents in my mind.
