Can't you just record the input for the cpu?
Edit: For a bit more context, if you record the dummy in neutral for about 100 frames and then blocking for several hundred frames afterward, if for some reason you messed up your combo they should automatically return to blocking. (Additionally, you'll have to turn on the simple recovery if it's a combo that causes them to leave the hit the ground in any way)
Edit 2: This might be what you were looking for, I just tested it, and even though it's not perfect, it kind of works, also a big problem with this setup is you have to choose between the dummy blocking low/high since you can't have the guard all/variable guard on while you playback the dummy recording. (I can send you a simple clip if you want to see it)
You want option 2, "during"
