I will point out that this is not possible in the general case.

Let me get this straight.

You are being sprayed with over 200 packets a second in a random
sequence. You are to reload your Cisco's access lists 200 times a
second over a telnet based expect script or something similar?

This doesn't strike you as impractical?

Admittedly, it is difficult

It is impossible using the stated methods.
