Echo, I am pleased to say I applaud the version 2 map you have put out there. Everything looks like a major improvement to what we currently have. As a principal, I would push for deletion and merger of more unused systems, though each must be looked at on an individual basis.
However, there is one very important flaw I see in your current layout for the systems. I believe the deletion of the jump hole from Omicron Gamma to Omicron Kappa should not be carried out. This jump hole is central to corsair lore in that it is surrounded by the "Graveyard of the Innocents." Seance times immemerable, corsair children have been sent to this jump hole to prove their worth. One of the most bone chilling experiences I had in vanilla freelancer was taking the time to read the info cards in that graveyard, and then realizing that nomad ships were showing up on my scanners.
Deleting such an important link to the nomad systems, present seance vanilla, and part of the fabric of corsair lore should not be done lightly. I strongly advise against doing such and push for another solution, if possible.
