It poped in the last game of the championship match in Milwaukee so we want t change them to 30s. Problem is we will have to redo the entire PDB to make this change at Atlanta if we cannot find 30's that will fit int he 40a slots. Having only about 2 hours for pit setup and robot inspecctions and needed robot changes in Atlanta this year, we were looking for an easier way to switch to 30's.

I don't know for sure, so take my advice with a grain of salt, but I bet you were pulling more than 40 amps per motor at the time. I've been told the breakers don't instantly trip once 40 amps are drawn, so instantaneous current could get higher.
The best way to fix this issue would be to decrease your current draw, rather than forcing your circuit to break earlier. That would just change the issue from "my robot can't move anymore" to "my robot stops every few seconds", which both suck.
