Engine Engine swapping

I have a Husqvarna YTH20F42T with a Kohler SV600S 20hp engine that is locked up. I also have a Craftsman 917.273662 with a Kohler CV730S 25hp engine that runs. Is it possible to swap the engine from the Craftsman to the Husqvarna?

If they are both twin cylinder then it will be easy. Just make sure the shaft is same diameter and length.
