That would mean major piping works!
As the modern boilers modulate, is the 2 boiler approach justified (other
than by the "only one service is lost in the event of failure" argument).

No it isn't.

For the scenario that you describe, stored HW is a much better option.
You may wish to upgrade the cylinder to a fast recovery type.

I did the exercise of changing boiler, swapping to sealed operation
and replacing the cylinder with a larger fast recovery type a couple
of years ago.

It doesn't need major upheaval, simply removal of the small header
tank and fitting of sealed system components. Very straightforward.
