Driving to DFW would have been your best bet. Now that the opportunity has passed, there's no way you're making your connection.
You'd never make the Lima flight either.
Your earliest arrive to GRU is to route DFW-MIA-GRU and you'll get to GRU at 0515.
Honestly, I'd just take the 24 wait and fly DFW-GRU tomorrow at 2120, which puts you in GRU a day late a 0925.
