I don't see any difficulties in getting back her alien status from you.
Honestly, I am a green card holder for almost 13 years, and I never stay in the State for most than 2 weeks each trip. and I only back to the State one every 2-3 years. I have renew my green 3 years ago in the State easily. no question being ask.
As you know, to get a travelling visa to the State is really depend on the immigration officer, under normal case, if she can proof that she go there to attend the wedding party and she also show them her expired green card, she should be okay to get the visa., if not, try again the next day, I don't see why the immigration will reject her.
But getting a visa , doen't mean you are guarantee that you will be able to entre the State as Custom Department is totally different, they can reject anyone with a valid visa, except you have green card or citizen). They can reject for no reason. I have experience once when I was having a business visa to go there for business many many years ago, they said I went there too many time??? and a friend of mine, her mother is European from UK, she was rejected to enter with no reason, even thought she book hotel in the state.
Is true that the custom is very tough after 911. But it's all depend on the custom officer. Don't worry, she should have problem in getting the L1 visa for sightseeing.
