On the other hand the SS Great Eastern, while only a passenger liner, was faster (at 14 knots top speed) than any ship the Union had and probably could have run over the Monitor without any risk of sinking.
She actually did sail passengers to New York during the Civil War. But lost money at it; eventually ending up as a cable laying ship due to her vast (for the time) size and range, and the maneuverability from the paddle wheels supplementing her propeller probably didn't hurt when fishing for a broken cable.
On a slightly more serious note I think the Crimean War screw batteries were in many ways comparable to the early Union and Confederate coastal ironclads; and the British and French had built a number of them in the 1850's to duel with Russian shore batteries. If they could have gotten those across the Atlantic they were probably a better design for coastal combat than trying to make HMS Warrior fight a screw powered ironclad in confined waters.
