Lenin lives longer

Point of divergence is Aug 30, 1918... Fanya Kaplan is unsuccessful in her attempt to assassinate Vladimir Lenin. Without a bullet lodged in his neck, Lenin does not suffer the series of strokes that ultimately killed him six years later. He lives an additional ten years, dying of a heart attack at age 64 in 1934, by which point the Soviet Union is on strong economic footing and industrializing at an an astonishing rate. Without a Ukrainian famine brought on by Stalin's vindictive and murderous policies or his gutting of the party's old guard through the Great Terror, the CPSU is much stronger ideologically and administratively. Upon Lenin's death, Sergei Kirov succeeds to the leadership, ushering in a period of increased consumer goods production and raising the standards of living of the average Soviet citizen.

Does this seem a realistic interpretation? Would the Soviet Union be much more peaceful had Stalin been removed by Lenin as he had wished in his will? Lenin was not a saint by any means but I believe from what I've read that he would not have enacted many of the vicious programs instituted by Stalin. Lenin's New Economic Policy was a step in the right direction, despite the need to focus more on industrialization. Additionally, Trotsky may have remained head of the Red Army, leading it against Nazi Germany, with an intact officer core (General Mikhail Tukhachevsky among them).
