Nahh, I don't think so. one object at 100MPH, another object at 10,100MPH, where deltaV is 10,000. Applying the deltaT to the field around the object wouldn't make that 100mph object go to 10,000mph.
That's not what makes rockets go so fast. It's PV=nRT. PV/nR =T deltaPV/nR =delta T, which is what you're doing, so there are 4 variables to absorb what one deltaT can absorb.
