Aaand, to put it all in one place, here's my proposal for RA 6.0.
1)Take DaBabes Scen 28C ships/classes list, and apply to it RA's additions. Thankfully, I already did much work regarding Japanese cargo ships, various auxilaries, etc, for the Perfect War ship list, which can be applied to RA pretty much as is, so only major combatants and escorts need to be redone.
1.1)Scen 28C reduces cargo loads for all transports and tankers by about 1/3. To avoid a premature bankrupcy of Japanese economy in RA, where Japan has less fuel reserves, and to keep the overall spirit of the mod, I propose reducing fuel stats for Japanese cargo ships and small auxilaties by about 40%, if proposal (1) is accepted, which will make them go the same range on less fuel.
2)Let's stick to the original RA complement of extra major combatants: 3 Shokaku-kai carriers, 2 Kawachi battlecruisers (with the second one renamed to Kasuga) 2 new Tone-kai CAs, 4 Oyodo-sised CLs (using the proposal from the previous page, named Yahagi class, to separate them from the stock Aganos). The Yahagi class is pushed into construction a bit earlier, because of a clearer vision regarding its specifications, but not too much earlier, because the shipyard intended to build them probably needs reconstruction... In addition, 5 large APs are provided with an option to convert to Kayo-class CVEs, the fist two on 42/12, the rest on 43/6. Conversion takes 270 days. Removed are Shinano, Taiho, all of the original light and training cruisers, Kayo, Army CVEs. Let's look at the resulting shipyard load in the mod:
You might see, that several ships should most likely arrive later than they do, including Renkaku (3/44, this all of the following dates are approximate, of course), Kasuga (12/43), Yahagi (6/42), Oyodo (8/43), Noshiro (10/43) and Sakawa (12/44)
On the other hand, Ryukaku (10/42), Kawachi (11/42) and the second batch of Unryu-class carriers (late 1944) can be made available earlier.
I do think that this makes the Japanese program less loaded specifically for 1943. But on the other hand, much fewer valuable ships will arrive hopelessly late.
2.1)This program is actually already a fair bit above "realistic" Japanese construction capabilities. You might see, that shipyards in my table work almost without pauses, laying down new ships immediately or almost immediately after the previous ones leave their slipways (except for Mitsubishi's shipyard in Nagasaki - that's because we need a shipyard set aside for all the conversions). IRL, it was not so. This is one reason I'm against adding new major combatants beyond the original RA vision.
The other reason is that, IMO, Japan, unless defeated badly and early, needs extra destroyers and small amphibious ships much more than it needs extra cruisers. In my oldest RA game I'm now forced to avoid engagements because I cannot build balanced taskforces anymore. Thankfully, the current versions of RA already provide for this, to an extent.
3)I also think, that, even despite the HI tax, the side of IJNAF pilot training program should be increased somewhat. 300 pilots/month in 1944 is not enough.
4)My proposals regarding the light forces still stand.
