H1B Dropbox & Stamping - How to share H1 visa recently approved during the dropbox appointment

I’m an Indian citizen working on an H1-B visa(Currently in the USA) for the employer A and scheduled the dropbox appointment in March 2022 using employer A latest approved H1 petition number. Now I got another offer from another employer B and they’re filing the H1 transfer + premium processing now and hopefully it will be processed in Feb.

Consider if Employer B petition is approved, Can I create a new DS160 using Employer B approved H1 petition details and share the new DS160 at dropbox interview for the stamping even though initially given DS160 details got changed? Will it be okay ? Can you please advise.
