Yep, this should be perfectly fine...
the only trouble could be if you get an RFE for Employment Verification Letter....but, then you get abour 3 months to reply to the RFE (as per old USCIS response timelines)....that one can responed to with an updated Job Offer Letter - based on your employer at that time. Since, you are retrogressed, chances are slim that they will issue an RFE
