Cap Exempt Petition even if the petition is revoked

H1B petition got approved for the current year and also Visa stamped. I have never travelled to US on this Visa. Now I have left this company and another employer wants to offer me employment based on the previous filed petition. Employer B wants to file premium processing and cap exempt. Is that Possible. While leaving Company A I had to surrender the petition files but I do have the receipt number copy. Is cap exempt petition possible?

Yes, Cap-Exempt is Possible for an Approved Petition, irrespective of Revocation/Withdrawl
