Interestingly the way modern cars are built you could do a powertrain
swap with relatively little effort. You do need a special lift but other
than that it's a few bolt and some connections to sever but drop out,
lift in.

Yes indeed. The other thing about electric motors is that they are at
100% torque on power-up. Gasoline engines on the other hand has an
optimal power band where maximum torque is available.
