No reason you cant. You can send 2 applications now. But because your 1st application was received, you'll get AOR. As I see, there are two premises where you will re-send application - 1) application lost. Till now, there has not been any concrete evidence of any application being lost. and 2) you believe that 2nd application will receive AOR before 1st application. you can be the judge for this.
Even though I say there is no real need, I'd have to say that there is no real disadvantage. Cost/hassle/time if you consider that. Then there is confusion for the officer, so make sure you have explanation letter at the top. But those are minor points.
Know what? assuming what? Everything in my reply is based on observation on this forum and the observation in the spreadsheet.
