You have access to good map in russian ! It a chance, because I don't read russian at all, I could only rely on english or french map.
Actually, I believe that by the end of our work, you all will have learned Russian alphabet and will be able to read these Soviet maps easily.
At least, my English son-in-law learned Russian alphabet in a couple days and so he is able perfectly to read menu in Russian restarans.
They're really quite good, these three maps 1938-1940 / 1941 / 1942
1938-1940

They cover the whole of Europe and even partially capture the Middle East and North Africa.
The second two maps are comfortable for the eyes, good for viewing from afar, do not have secondary roads, but the main highways are highlighted in yellow and therefore differ good from the "improved dirt roads".
And the first 1938-1940 map even contains minor poor country roads of local importance for USSR. Now I always check the connections along it, because where I thought there are no roads, it turns out they are, although poor and winding.
Do you consider the size of cities for implementing your modifications ? Does the DH map was already reasonnably done about important cities in USSR ?
I am using the first two maps for a general understanding of the logistics of the region and the size of the cities.
Naturally, I try to choose a large city for the name of the province, if it is suitable as the main logistics hub. But this is not a law for me. If a large city is not suitable for the role of logistics hub at all, I can easily assign a small village to this role, but which is located at a key/strategic crossroads in this area.
For example, when I moved Bryansk to the right side of the river, the question arose - what would be the name of the old province? There is a really large town Ordzhonikidzegrad opposite Bryansk, the the only large town in this province. But it is completely unsuitable for the role of the main logistics hub of the province. That's why I named province as Kirov - it's a key crossroads of strategic roads in this area, but the town itself was officially recognized as a town only in 1936(!), it's a fairly new born small settlement.
In other words, it is not absolutely necessary for me to put large cities on maps. If large cities are in a good logistical location (usually they are), it's OK. If they are away from the key roads and intersections of the province, I can easily ignore them, for me this is not a sacred cow.
Does the DH map was already reasonnably done about important cities in USSR ?
Therefore, for me, such an aim is not worth it at all, it takes absolutely no difference to me whether all major cities are mapped or not.
I care only about high-quality implemented reasonable and some times even historical military logistics.
Will you check the Soviet Far East in case of Soviet-Japanese war or it is well done in your opinion ?
In our old multiplayer community, Japan's war with the USSR (before the fall of Stalingrad and Moscow) was always prohibited by the rules, so for me this is a very secondary region for improving the map.
I think we should first create the most sought-after war zone - European theater. And after that, we can finalize this first version ('Light version') of the map so that the modders can already transfer their mods to it and release versions on the new map.
And then we can safely continue work on the rest of war regions.
