Only as stupid as having two engines in your car.

What if it was cheaper, and possibly more efficient, to couple two
smaller engines together?

Isn't that basically a V-engine (V6, V8, V10, V12 etc.)

Nope, those just have different timing between the banks of cylinders
firing.

You do see lots of boats and planes with multiple engines,
but that's not so much for cheapness and efficiency, its more
so there is still something left to use when one stops working etc.

You do see multiple engines almost universally with the
heaviest trains, but that's for different reasons to do with
getting the power delivered to the rails via the wheels etc.

You do also see multiple engines on the heaviest machinery, particularly
with diesel electric systems and hydraulic wheel motors etc.
