Better to ask the mods first before you potentially waste your time. I think since the engines are unique you should be fine, but it is good to double-check.
I haven’t seen mention on this thread about the upcoming low tier Hungarian WW2 air subtree being added next update, it’s 7 new planes, with only one being copy-paste, and several very interesting additions such as the largely forgotten WM-21 and the obscure prototype fighter WM-23. I think these additions show a pretty serious effort by the snail to model WW2 stuff (all 7 are WW2 aircraft, and all are researchable) and give us hope on this topic.
Update :
has been suggested thank to @Grzegames for proving sources / book images 💗💗💗


another reason

i think the G10N would be fine gajin could choose different engines
Spoiler
Nakajima HA54 engine (5,000hp in take-off) ×6
Variant 1: Nakajima HA44 engine (2,500hp in take-off) ×6
Variant 2: Mitsubishi HA50 engine (3,000hp in take-off) ×6
i did add other engines types in the suggestion





Mitsubishi HA50 engine
Extra
HA54 engine cooling test model from report
I remember I wrote about G10N, but it wasn’t accepted, even provided all the sources and evidence :(
But alas… I hope it’ll be accepted here at least.
Weren’t there different configurations of the fuselage? Well, at least we can get the Ki-91
suggestion was declined maybe because i did not give enough information or a good reason?!


maybe they need more proof i don’t know were i could find more proof of exiting parts for it :(
Yeah, actually now that I remember, I don’t think the Ha-54 engines were ever completed. I don’t think we can get any of the more advanced bombers other than the Ki-91 and G8N variants.

Are you in the Japanese vehicle discord?
There was the Ha-50 engine that was potentially built for the Kawasaki TB bomber, but that’s kinda dubious
Personally I think the G10N suggestion need to be done by someone knows better and know more history am not qualified for this suggestion.
heres only stuff i found about that engine from online source
I don’t use that store / website i only use war thunder forum and whats up but that’s private with family only.

When work on the Nakajima G10N was discontinued, three of the six Ha-54 engines were ready. They were built specifically for this project. The competing Kawanishi TK did not have specific engines.
So the suggestion about the G10N should be possible. The same with the Ki-201. Both vehicles were in the initial stages of development (engine development). It’s probably necessary to make a good case that the G10N was an unfinished prototype and back it up with sources. If I weren’t angry with Gajin, I might have written this suggestion.
I was not aware the Ha-54 was built
Here above you even have photos of the preserved Ha-54 engine that was found in Japan.
Hmm, Ha-50 was a different engine from the Ha-54. Ha-50 was a 22 cylinder, and the Ha-54 was 36. Though I admit I don’t know if the Ha-50 was for the G10N or not
I honestly don’t know where the Ha-50 engine suddenly came from. Sources I’m familiar with say the Ha-54 engine was intended for the G10N.
By the way, I found this:


As promised, a 5th anniversary special.
Funny. the last French made tech tree aircraft from WW2 added to the game is, I believe, the BR. 693 added in october of 2019. It’s been a while as well.
I wouldn’t be surprised. Gajin ignores smaller countries. We get placeholder content, C&P, or nothing. Meanwhile, large countries get their planes, tanks, and helicopters. The French don’t even have their D.510 as a TT vehicle.
