That's highly unnecessary. A regear is so much cheaper and will give you power. Not to insult you but do you understand how a regear will significantly improve power transfer from your engine (which is a strong engine) to your wheels?
And do you know what's required for an engine swap? It's not just a pull out the old, bolt on the new.
