Here is another possibility of ending the bombings, which as we probably have figured out are motivated by the sums of money the Saudi's are paying more than a sense of injustice. That is just the "public face" to get their families more money than they could earn in 10 years.
The second solution?
What is the disposition of the bodies? Do they get returned to the families? If so, stop it. Publicly bury them in pig fat and feces, in a place they annot be exhumed. Presumably a place under Israeli control. Hell, stuff the parts (that is probably all that is left most of the time, if they really know how to make a good bomb...) inside of a pigs carcass, filming the whole thing. Then tape the burial and broadcast it so that all know they will NOT be going to meet Allah. As the Soup Nazi would say: No virgins for you!
This way, lives would be spared. I am sure the outrage would be the same, and perhaps worse. It would just go to show you what people value more. Life just doesn't measure up.
