No its a bad idea, if she comes as F-1 and you get married here, she will be considered having pre-concieved immigrant intent which is not allowed in F-1.
If you apply sometime later to be safe say six months later, if you file at that time then by the time a visa number will be available for her it will be about three years, and for all this time she will have to maintain F-1 status, she will also will have to stay in US for all this time also as she will not be able to re-enter as F-1 again after you file for her.
