Not in the least bit possible. Guns, the Pact was not capable of doing that in the 1950s - and, quite frankly, at any point in history. Really, you need to look at why such an event was not undertaken by Stalin in 1951 otl.

Soviets are not capable of launching invasions in any form but land. Really no question, there.

Troops from Japan would not be sent like that, either. Logistically impossible.
