i am in the same boat. i submitted my app with loe, rejection proof, new submission proof, proof of initiation of state pcc for NJ and CA. ii did this in hopes so that if my second submission gets rejected, CIC *may* nto ask for fbi pcc anymore and *might* just be satisfied with state pcc(s). but dont rely on this. this is just a consolation plan - CIC could ofcourse enforce to get fbi pcc.
read pages 190 and 191 of this forum, especially post #2845 and till about 25 posts atfer that. you shall get a clear idea of what state pcc are good for and what not.
I would think doing that would be most convincing since you would be supplying a copy of your new submission, old letter, and state pcc in my opinion. Think about it? Do you think that raises or lower your chances with more evidence to validate your background. Remember the purpose is a background check. Of course with the fbi pcc it covers the entire states because a broader check is done. But you are looking to increase your chances for visa officer consideration of extension and very likely full acceptance as a substitution. But this all depends on the VO discretion. State pccs should not be used as a primary method. *disclaimer

When your fingerprints are within the processing date, email fbi on the status of your fingerprints. They will let you know if the prints were accepted or not.
