Sorry, everyone has the right to change their Will, right up to the time they're on their deathbed. If everyone wants to sign such a document as you suggested, then it can be done, but I doubt it would be enforceable against anyone's estate that made up a new will anyway despite the agreement. The best thing anyone can do when they makeup a new Will is to have the signing video recorded so everyone can see they did it without coersion or undure pressure being put upon them. That will at least eliminate claims of duressafterward. Good luck.
