It seems unlikely that Stalin planned something like this. Consider that after the Polish-Soviet War ended any future plans for Bolshevik expansion into Europe, Stalin was the proponent of "Socialism in One Country," and worked from there, while Trotsky was the leading figure of the world-wide revolution. While this doesn't mean Stalin totally ignored the international spread of communism, or that a policy put forth in the 1920s was never going to be altered, it does suggest he was foremost concerned about internal matters.

There is also the issue of the percentages agreement with Churchill. This policy was supposed to limit the spread of influence for both the West and the USSR, and Stalin did initially agree to it. Granted he did renege on this agreement, but the way he did so (waiting nearly three years, in the case of Czechoslovakia, to implement a Communist takeover), also doesn't help this idea. The Molotov-Ribbentrop Agreement also doesn't contribute much, as it limited Soviet influence to those regions formerly part of the Russian Empire, territories that were widely regarded as being "reincorporated" to the USSR, and not an expansion per se.

So overall I would suggest that this was not really something planned, and not something I've come across in my study of the era. There are too many things against it, too many variables to account for (the very real threat of the Soviet Union being conquered in 1941, for example, or Stalin's insistence that the Allies invade the West; don't think he'd demand that if he wanted France for himself), to really make this theory credible.
