The general consensus is that the old 2.5 mH probably would blow open in such a
case?

Neither. if you are asking about the power output of the amp. It should
have enough current handling capability to cause the PS to blow a fuse
or shut down in case the blocking caps fail.
I don't think I missed anything.
It's only function in an amp is to get the plate voltage from ever
getting to the coax connector and hence to the antenna if the blocking
caps fail.
