Can I change project after got selected in the lottery?

Can I change project after got selected in the lottery and after that the status is RFE and asking for sow kind of document for that project only and my employer Doesn’t have a valid sow for now for that project.
And please suggest what else will work for now?

Generally it is not recommended to change the project details during RFE phase of H1B. Its better to talk to your Attorney on how to handle this.
