Yes but spamming atomic bombs are ahistorical, the US only had a few by the end of 1945. The atomic bomb should be a war winning weapon, which it was historically. And I don't want an atomic bomb to cause instant capitulation, only if the enemy has control of core territory, low stability/war support, low ratio of strength compared to enemy, etc.
I think you may want to go back and reed my initial post because I argued I would want to see one or two nations total in the game to ever develop an atomic bomb by gatekeeping the tech with access to uranium, high civ cost (like 100), and those with the scientific community available to actually make the bomb. Historically that was the US with the aid of the UK and Canada.
I would never want to buff the weapon without making it way more costly to produce and costly on per unit basis.
