When I had a priming pump issue with my old pump set-up,
The J&S safeguard knock controller performed a similar rescue. It is a way cruder means of intervention than your sophisticated ECU, but still it was money well spend.
Engine spit flames and bogged, but nothing more happened thanks to an instant 10 deg pull of timing on the offending cylinders.

Any high strung FI motor should have proper knock control and ideally even more layers of safety as you have described.

Overall I can only second what you wrote. Life, Motec etc offer amazing capabilities these days.

I am not a 100% keyboard warrior as most of the stuff I write comes from my own literature research and experiments on my own FI engines over the last 10+ years.
