My thoughts are... You are very optimistic in thinking marriage solves everything. It's not true.
The best case scenario - employment will never come up. But because you got GC based on employment, the chance is it may come up.
A slightly worse case scenario - USCIS will try to take the GC away. If succeeded, you'll have to become an LPR again and may have to go through waiver process to become admissable.
The worst case scenario - you will lose the status, will be ordered to leave the country and will get a forever ban for getting any immigration benefit if fraud was found.
Immigration benefit is a privilege, not a right. USCIS, if can prove there was fraud involved, may strip all immigration benefits and never issue them again. Marriage to a US citizen is not a silver bullet solving all problems, especially if fraud is involved.
I'm not accusing you of anything, just listing potential bad scenarios and their outcomes.
