Even with NS boost it will be over 500 jumps to me. That is 16 hrs to jump (no sleep, no eat). You can relaxed mine 100t / hr = 1600t during that time
It would be a lot of jumps.
I don't know what would make it worthwhile. Along the neutron plane it is fewer jumps, but you still have to fuel scoop. Also, getting to the neutron plane would be a lot of jumps, but you can get there with half the jumps if you use fuel injections. Though it is a bit aggravating to do so manually, but I suppose that a route could be mapped out in advance and have a list of star systems to the neutron plane.
Check my math here if this is interesting to you. I think I did this right.
Here is a T-9 (672 tons cargo)
It could be made more efficient and of course it has max engineering. It on gets 30LY when laden. That would be 120 on the neutron plane, but only 60LY with 100% fuel injection getting to the plane. It consumes 8 tons max per jump so it can get a max of 8 jumps between refuels. That would be 30 from the scoop and then 840 boosted, so 870 max on each tank. So that would 11.5 tanks for 10,000 LY on the plane or about 92 jumps. That is with maximum efficiency, but it would take more since it will never get a perfect 8 jumps per tank. (not sure about this since the fuel efficiency improves as you burn fuel)
A type 7 (224 tons)
This one gets 41 LY laden, but you could use the double engineered FSD for an improvement. As it is, with a regular max engineered FSD it consumes 5 tons per jump, max. That means 6 jumps on a tank. 41 from the scoop, and 820 on the neutrons for 861 per tank. That would be 11.61 refuels per 10,000LY or about 70 jumps.
I guess you could build out either one with some extra fuel tanks so that you don't have to scoop as often.
Type 9 (560 tons cargo, 192 tons of fuel)
So, carry a smaller AMFU and get rid of some things and add 128 tons of fuel for a total of 192 tons of fuel. That gets 24 jumps per tank. Still getting 30 from the scoop and now 2760 on the neutrons for 2790 per refuel. So, it takes 3.58 refuels to arrive or about 86 jumps per 10,000LY at max efficiency.
Type 7 (224 cargo, 52 tons fuel)
Added an extra 20 tons of fuel. That brings it to 10 jumps per refuel. Now getting 40LY from the scoop and 1440 on the neutrons for 1480LY per refuel. That would be 6.7 refuels for 10,000LY or about 68 jumps.
The fuel efficiency would improve as the fuel was burned, so it would probably be better to recalculate the route every 5 to 10 jumps. That would probably lower the number of jumps some, but I don't know by how many.
At 50,000 a ton, 560 tons would cost 28 million. So, 125 million for a little more than half a full tank or 250 million per deep space full refill (per 10k LY). Is that too much? I hear people make billions a week these days. Maybe it isn't enough.
Well, I guess people with a fleet carriers could venture to position their fleet carriers on or near the neutron layers and buy Tritium from players full time and then mark it up and sell it to other fleet carrier owners who could jump into the system and make a couple of T-9 runs between. I don't know how you can advertise that service though or how to advertise that you are paying 4x or more for the delivery of it. Some fleet carrier owners are making enough money that paying 300 hundred million or more for a full tank would probably seem like a deal.
