Higher powered microwaves would require higher powered electric
outlets, probably 220VAC (in the USA).

Not a problem in Europe where everything is 240V. Another reason you ought to stop that low voltage crap! Do you seriously have to hard wire all your washing machines, dishwashers, tumble dryers, etc, etc? And what on earth do you do with hoovers?

Also it is questionable whether higher powered ovens would be
practical for use. Getting warming times down to a couple of
seconds might not be a good idea. More speed is not always better.

It can take 5 minutes to warm something from frozen to eating temperature. I see no reason that couldn't be made into 2 minutes.
