With this, you would potentially be double(or triple if you include road tax itself) dipping on tax though. You would be paying for milage + Irish tax on ‘fuel’ when filling up in Ireland.
With petrol, you would be paying Irish tax filling up & driving there, not both.
You would pay UK duty if you drove on Irish roads with a fuel tank filled in the UK.

Maybe an offline GPS ringfenced mileage tracker to be reported at MOT. Only counts UK mileage, and tough to cheat.
I can see that causing a proliferation of illegal GPS jammers.
… And lots of stories about the government having gos trackers in all electric cars
Then opt-out of the tracker and pay based on raw odometer readings.
