It is not an ideal situation, but it may work with relatively close timing. Other than obtaining a non-immigrant employment based visa to cover any gap between the OPT time and filing of an I-140 and hopefully I-485 if priority dates are current, there isn't a real alternative to your situation. If everything moves quickly there may be a chance to make this happen in time. If you are married before a green card is issued, both spouses can obtain the green card based upon one PERM approval. Interviews are fairly common but not an intensive part of the process. If I can be of further assistance please let me know.
