OK, you will not be renewing anything at the embassy in France, they will maybe issue you a single entry (90)day Non-O visa and then when you come back you would have to season the 800k for 2 months again and re-apply for a yearly extension.
You are supposed to wait in the country until you are approved. However, you seem hell bent on bending the rules, so do whatever you want, and hopefully when you flit back to Thailand because you can't wait, they will ask for more details and then deny your visa because they will tell that you have left the country!
