A yellow skinned, white egg laying dual-purpose bird sounds like a worthy project.
If I were doing it I can see two different approaches I'd take.
The first would be crossing White Leghorns and White Plymouth Rocks, especially if you could find some that grew to a good size. The old broiler lines are probably gone, but I see plenty of show birds that make a very nice size. I'd select for egg size, rate of lay, sexual maturity, and mature size. I don't think it would take very many generations to come up with something good.
The other approach would be somewhat more difficult in the beginning, but might reach the ultimate goal a little faster. Pick a white feathered, yellow skinned broiler cross, either straight forward fast growing Cornish X or one of the slower breeds if you can find one that is white feathered. May need to keep them on a restricted diet to get them to breeding age. Just pullets. Once they are ready cross them with a White Leghorn rooster. Select as per what I mentioned above.
Either way in a relative few generations I'd be willing to bet you could come up with something that would breed true and would lay decent, make a good size in not too terribly long a time.
Now how much interest you'd get in the greater poultry community I cannot say. There is a decided preference for brown egg layers so you may be slowing in gaining wide spread acceptance.
Still a nice project though. If anyone got it off the ground I'd be willing to hatch them out and see if I could find any local interest.
