Sorry, I made an error in multiplication - it's 20x100 kg.
Sources dealing with bombs in detail are unfortunately rare and incomplete - I've found an info about 10 internal and 3 external pods in 2004
Il-4 book from
Voyna v vozduhie series, and about 14x100 kg variant in Kotelnikov
Il-4. Vozdushnye kreysera Stalina. I'm attaching a cross-section from the second book. I've been researching Il-4 for Polish Wikipedia purpose for last month, hence my interest in that plane in particular

Also if **I** can find corroborating evidence the IL-4 was used in combat earlier than 2/42 then I will change it but that remains to be seen

Immediately following the German invasion in June of 1941, the DB-3 was the only twin-engine bomber that the Soviets had in their arsenal....... In 1941-1942, the Ilyushin Design Bureau set about radically redesigning the airframe, wings, and fuel system of the outdated bomber. Initially marked for designation as DB-3F (Forsirovannyi or “boosted”), the changes made to the bomber of the 1930s were so significant that in March of 1942, the outcome of the DB-3’s transformation was an entirely new aircraft: the Ilyushin Il-4.

The quoted page is just wrong. Wikipedia
https://en.wikipedia.org/wiki/Ilyushin_Il-4 presents correct version, quoting references, that DB-3F entered production in 1940 and only in 3/42 it was renamed as Il-4. However, the problem with DB-3F / Il-4 entrance date is in fact secondary. The point is, that ordinary DB-3 carried the same payload, but maybe we don't need the aircraft with bigger bombs before 1942.
Besides, the statement, that "Immediately following the German invasion in June of 1941, the DB-3 was the only twin-engine bomber that the Soviets had in their arsenal" is wrong, because there were lighter Pe-2 and Yak-2 in service already, not mentioning SB and its later variant Ar-2... It might be accurate concerning long range bombers, but Er-2 entered service just in June 1941 and obtained readiness in August.

...that said I think I have a solution that will work for the 4 weapon slots used by the DB-3....5X 100kg + 5X 100kg + 2X 250 kg + 1X 500kg == 2000 kg and uses 13 hardpoints. The DB-4 will use 5X 100kg + 5X 100kg + 3X 500kg but PLEASE understand this endless nitpicking is GETTING OLD

Fair enough
Adding 1000 kg bomb and two 250 kg might make too devastating effect on the first hex.
Then we don't need heavier variant before 1942, and we can stick with these two planes with modified loads.
