Getting inside of a Permit Locked Nebula: Ft. Cone Nebula

So I am out in the orion nebula. I have decided to visit the thargoid-guardian battle ground and the thargoid structure 400ly from here. Then I thought abut something: what would happen if I got in the middle of a permit locked nebula? Then I thought of cone sector: the perfect nebula for this. A couple systems in the middle un-permit locked, so it's possible that I can get there. I have an 80ly DBX that I can ship over here, it has 320ly when neutron boosting. So I could easily get there, right? If the cone nebula is surrounded by 200-300ly of permit locked, all I would have to do is get as close as I can to the farthest un-permit locked system inside the center, so theoretically it's possible. Any confirms/debunks of this? I'm pretty sure it may be possible, unless all the neutrons nearby are permit locked or it's a distance greater than 160(jump range with jumponium). If it doesn't work, any other nebulas I can try this in? Any help would be appreciated! o7
