Hi! May be so.G5N was designed based on DC-4E.
It's true that Japanese aviation had no experience to design such a big aircraft at the day.

By any chance was coastal mine-laying one of the intended roles for the Shinzan? And was the 4,408-8,816 lb bomb-load projected or realised?

Hi I can't find any Shinzan's coastal mine-laying role by Japanese internet site. Shinzan was used as a torpedo carrier to the southern front. It could carry two 95- shiki submarine use torpedos(3,330kg total).  93-shiki torpedo was more heavy.

魚雷 means torpedo.水上艦艇用 means for ships, 航空機用 means for aircrafts, 潜水艦用 means for submarines.

"It could carry two torpedo(3,330kg total)"

Then one torpedo would have had a weight of 1665 kg, quite heavy for an aerial
torpedo, i think. Was a special type envisaged for the Shinzan ?

Hi! You are right. I am not sure which type torpedo Shinzan carried to the southern front. It might be aircraft use torpedo.

Japanese aerial torpedoes were 800 KG (@1700 lbs) if I remember correctly.

The answer probably is, that, as blackkite wrote, the 95- shiki torpedo was
a type principally used by submarines. But such a torpedo surely cannot just
be used as an aerial torpedo with intensive modifications. Maybe the Shinzan
was intended just for torpedo transport and not torpedo attack ?

Hi! Of course torpedo transport role only. It's impossible for low performance Shinzan to attack ships by torpedo. ;D
I think submarine torpedo transport by Shinzan was good idea,too. Because it's not necessary for submarine to return Japan to charge torpedo.
It's safer and faster than the surface transport.The weight of Submarine torpedo was 1.7ton.

Ok, this misunderstanding is cleared, my fault, sorry .
But wouldn't a flying boat have been a better transport then ?
This way of torpedo transport would have needed quite good
infrastructures, I think.

BTW, mass drops of long range torpedos against enemy fleets
(probably at night) was considered a viable tactic by some air arms,
although never used in anger, AFAIK.

Hi! Fugaku transport version. She did not have turbo chargers.

Did you tried to do a Turbojet powered variant?

Hi! I believe there are no evidence for existence of jet powered version of this transport.
