You can, and it would work. But keep in mind, you're taking that small displacement engine from a low-weight vehicle, and putting it in a much heavier vehicle... it will be considerably less efficient... You might want to consider exactly what it takes to move 2200 lbs.
Weight reduction will be key in determining whether you can use the MX-3 effectively or not.
Keep in mind that reducing gearing is not always the answer either. I can personally vouch for this.
