Doubt that. Livestock eats up much more energy than its meat gives back (i.e. you would have to feed 7kg of soy protein to get 1kg of meat protein).

With insects such as Mealworms that's much easier. They basically eat anything and they turn it almost 1:1 into valuable protein. Also you can raise them pretty much everywhere, even in crammed indoor farms without it being cruel.

It's sounded more like you were imagining wild crickets being collected from grass fields or something... which is obviously not a good solution.
