I’m not certain how Rescue Nation should be set up, maybe the best rescuers to go to would be the corporation that runs a rescue operation in Wormhole Space.
Rescue Nation would work by first finding ways into each Triglavian held solar system via wormholes. Once in a freighter would be contracted to Hot Jump your items out of the system using an outbound filament to the closest High Sec system under New Eden control. The gutsy and most ^&%$ stirring move would be Hot Jump into the Triglavian system using an inbound filament. Either way is risky and is going to see freighter pilots lose their ships as well as pilots losing all they have trying to get out.
Unless CONCORD develops a new freighter that can exploit weaknesses, the Rescue Nation flights into and out of Triglavian space are going to have be escorted by EDENCOM using Skybreaker, Stormbringer Thunderchild and %#cracker ships. Normal ships will not survive the assault by the Trigs, Kubs or other upended %#hats in the system. I watched a video where a Capsuleer ran a T6 Abyssal in a Stormbringer and shredded it without taking hardly any damage.
The use of the EDENCOM ships being used to rescue trapped Capsuleers is best left to those who can operate the EDENCOM ships at 100% because anything less would not be an Elite Rescue Nation Capsuleer.
Watch out for the Zorya Tollkey though, she is sure to gobble up everything.
