you will not get your first 12 month extension that way and, if on a marriage Non-O, may never get an extension using that method at many Immigration Offices
The current extension will be invalid without the 800k for 3 months and 400k for the rest of the year plus starting the 65k now would only generate 11 deposits before the current extension expires. The OP will need to do a border bounce to end this extension and start with the Non-O again.
