After reading the replies so far, maybe I'm misreading your post.
Having said that.....

Frankly, I see no problem with your grand daughter's idea.
It's quite common for twin engine boats to troll all day long without
a engine, to save fuel. At trolling speeds you just don't need both.
But be ready to crank it up in case you need two to maneuver.
