I have had 3 week old Scarlet Shiner fry travel for a week without food and do great.
I had two month old Bluespotted Sunfish all die after missing food for 5 days.
I would try shipping in breathable bags with live food - paramecium, copepods, or a small species of daphnia.

I have no experience shipping small sunfish.

Want to ship several thousand little ones at a time. When they are old enough to feed but stll larvae, handling stress can give unpredictable results.

starvation was the definite cause of the fish loss?
These blue spots were not shipped correct?
I am of the understanding that many larval fish have yolk sacks that they feed off of, i would think ammonia toxicity, heat, and o2 depletion would be your main worries.
shipping in the winter may work, I would pack the fish in cold packs
for ammonia, i think you can buy commercial products that will absorb or lock up ammonia
other than pressurizing the shipping bag with o2, i cant think of how you can fix that problem
you may do a trial run on a very small scale
take the smallest drinking commercial water bottle you can find, and ship 100 larvae to your target. if they live I would try and do it with a plastic gallon water jug, with your whole shipment.
