Is there is an overall term used to measure a closed loop control system's reaction time? That is clock speed, sample rates, valve opening, slop etc. expressed as one value? Perhaps a go or no go type of answer with a fuzzy border.
Just a gut feeling says you should have bolt on "training wheels" till this child gets more mature. Perhaps a bolt on thruster pack on the nose with a separate controll, say kick in at 10 degrees and shut down at 5?

When the rocket tips over at what point will it be unrecoverable? That is using just main engine thrust steering with no thrusters for just steering. Thrust can't go negative and can only go so high. Have you modeled this?
If everything is operating properly, it is only unrecoverable if the cg moves outside the polygon enclosing the centers of the engines, or if the propellant sloshes enough to uncover the feed inlet, starving the engines. Theoretically, it can fly upside down and sideways, as long as it is accelerating enough to keep the propellant going to the engines. However, if it hasn't been able to catch whatever was wrong by the time it gets 20 degree away from the desired position, it probably isn't going to, because the control parameters are probably wrong.
