Answer:
It definitely would have an ironic mood. It would have the reader feeling a sense of dread, knowing what's going to happen at the end.
Explanation:
The entire story except for the end of The Lottery was like a cheerful mood. The town was all gathered for a pleasant gathering, the lottery. However, once you reach the end of the story, it takes a dark turn, having the town members turn against the winner by throwing stones at her. 
It would have an ironic mood once you read it for the second time because you know that all that cheerfulness and pleasantness of the town gathering is false, because they are planning to stone the winner because of tradition. Being ironic means that something unexpected happens, like the reverse of what you think would happen. It's like being sarcastic. 
For example, if you studied for a test for 10 years and then find out the test you were studying for didn't exist anymore, it would be ironic.
So, reading The Lottery again would totally be ironic. It seems like they're all having a good time, but really they're going to kill one of their own. This goes hand in hand with the second question, how would knowing how the story ends change the whole thing. You're expecting a lighthearted gathering, but really you know that they are going to stone someone.
