I hypothesize that all systems that have a blue star would be invaded, and contested to either Final Liminality or EDENCOM Fortress. This would split New Eden into many islands.
This means that logistics would be more of a nightmare than it is now, with trig low/nulls all around the path. This would mean we would have so much destruction that we cannot actually progress, therefore dissatisfying us. (Or we stay in one of the islands, which is equally bad). It will mean “highsec” would become an adjective of a system instead of a noun of the group of systems where we travel with little fear.
The idea though would be quite good. I propose something: We would be able to enter abyssal deadspace (but not the ones you do in gilas, but a “mirror” of New Eden, including systems and stars and all that). We would be able to get blueprints of a “filament” to abyssal deadspace from Trig LP or wrecks of Trig ships. We would be able to then use these filaments to enter a system in Abyssal deadspace, and the filament turns into a filament from any point in Abyssal deadspace back into the system the guy came from.
For example, we would have a filament called “Filament to ©†ˆø†ª¶∞” which would travel people to that system in abyssal deadspace, and if someone uses that filament inside Jita, it would create a “Filament to Jita” which could be used in any point in abyssal deadspace to go to Jita. This would allow people to travel from one island to another, while still meaning the travel is limited (as the initial filament has to be created in the other system and transported to this system).
My suggestion needs a lot of improvements (maybe jump timers, or that filaments to real space can only be used inside certain systems in deadspace etc), but maybe, just maybe.
P.S. We can make deadspace “shadow New Eden” with races and new content and all that.
