Regarding resource production, and how severely unbalanced it seems to be in the conversion.
Perhaps using something like one, or more of these:
#1:
-Vanilla Distribution.
#2:
-Each province from Vicky that produces an affiliated good will convert over to HOI to produce resources.
-These provinces will be weighted inversely proportional to the IC of the owner.
#3:
-Like #2 but be weighted inversely proportional to the IC/province ratio.
#4:
-Resources are distributed on a basis similar to how IC is converted. Taking into account, railroad, efficiency, population etc.
#5:
-Certain techs from Vicky will give countries more resources.
Reasoning:
#1:
Pro:
Resource distribution will still be historical regardless of what you have done to the poor timeline. Players have had plenty of time to grab resource rich regions and they know exactly what to expect.
Con:
The vanilla resource distributions were setup to help with gameplay as well as historical accuracy. In addition, resources were often historically exploited near the major industrial centers first while the colonies were used primarily for things that couldn't be produced back home. This left many resources unexploited simply because they were not near the major industrial centres of OTL. As the major industrial centres have changed so should the resource exploitation.
#2:
Pro:
Industrializing uses up a lot of resources. If a nation has industrialized then they would have fewer resources available then a nation that is still developing. In addition this still represents, to some extent, the distribution of resources.
Con:
Resources historically were more available in certain locations then in others, though still available. In addition this assumes that the Vicky distribution is correct. Finally this does not take into account that the same level of industry will use up more resources if it comes from 2 locations rather then 1. That was not explained well, if you need to ask for an example and I will oblige.
#3:
Pro:
Similar to #2, however one could assume that there would be a larger base to draw resources from. A small nation would have fewer resources then a very large one. The small one would burn up all of they're resources industrializing while a large one would use very few. Finally this does lessen the issue of the poorly explain con from #2.
Con:
Once again, resources historically were more available in certain locations then in others, though still available and this assumes that the Vicky distribution is correct.
#4:
Pro:
Nations that develop they're resources would receive more then those that ignore them.
Con:
Early exploitation often lead to the resources being used up. In addition, unlike factories, the production of natural resources is not linear. You can build another factory anywhere the land is stable but you can only put another coal mine where there is coal.
#5:
Pro:
Gives nations that research something of little use a bonus. Gives resource poor nations a chance to receive more.
Con:
Far from historical.
I also like #2&3 because it would give nations with few resources the ability to be important in HOI. In addition it would give the Industrial powers something to fight over. Whether through war or through diplomacy.
Regarding the term Affiliated good, that would be like oil to oil and coal to energy.
