Soft water is a must.
40 to 60 is not trivial. I can guarantee you the 60 will not fit where the 40 is nor will any of your exhaust suffice, you will probably require a dev permit as a result at which point you might as well go tankless.
2 X anything will require dev permit as well.
Tankless have reached the point where heating is very quick.
You won't save any material money on your bill, but you'll still have hot water after your kids have spent 20 mins each in the shower.
