In a communist victory TL.....

Do you think in a Communist Victory TL (Doesnt mean Soviet Victory), do you think the International would replace the UN or LN?

Assuming a complete victory, pretty much. In an optimistic timeline, it would be a world parliament. In a pessimistic/dystopic timeline, it would be akin to Comintern, dominated by one of the great powers.
 
In any scenario like this it would probably have far wider powers in terms of directing international trade and resources than the UN, so as to allow for more directed economic planning on a worldwide basis.
