I actually think about his a lot. I honestly think this is one of my best options. However they're not very broody from what I hear, can you solve this? Do hens genuinely refuse to sit on their eggs?
I've read of a few Leghorns that went broody, but it's not particularly common. That is part of why they can be such good layers: they are not taking time off to go broody.
You might consider having a few hens of a different breed, that do go broody, and let them do the hatching. Some people use SIlkies, but I don't like the feathered feet, crested heads, and silkie-type feathers. I've had several Old English Game Bantams from Ideal Poultry that made fine mothers. They would lay about 12-15 eggs and go broody. After raising chicks they would lay another 12-15 eggs and go broody again. I had a Black Tailed Buff Japanese bantam that did the same thing. A bantam cannot sit on as many eggs as a large hen, but she doesn't eat as much either. You can probably keep two bantams or one large hen for similar coop space/food cost, and have them hatch about the same number of eggs each year.
If you have a good laying breed and also a broody breed, it's nice if you can tell the eggs apart. Options include big vs. small, brown vs. white vs. blue/green, etc. That way you can choose which eggs to hatch, to get the kind of chicks you want.
Jerseys are 100% my favorite breed. The second best chicken for my situation would definitely be plymouth rock. But I am a man of pretty gamefowl gosh darn it!!
I see people suggesting a gamefowl roostesr with your Jerseys.
If you just want the color, without compromising egg production, you might use a Brown Leghorn rooster with your Jerseys. Same basic idea, but going to the other extreme on the laying/broodiness spectrum.
