Why do you need an alternative? Do you need alternative to make totalitarian group better like replacing Hitler with Goering and suddenly the National Socialism will get better? JW beliefs are fluid, it is one of the religious group out there that does not have defined theology. Whatever fits momentary explanation to WT and JW crowd is assumed to be Truth. It does not believe to the same principles I grew up and I have left 22 years ago. For example generation of 1914 that will never die to overlapping generation. WT is rotten to the core, and there is not much to salvage. Catholic church at leas run hospices and nursing homes, or taking care of developmentally challenged, while WT gives a crap about people who are sick, old, or mentally retarded.
If you believe in God who created everything around and this huge universe, do you really think that he will leave with humanity this poorly written book known as Bible? The book with laws that were already obsolete in late antiquity and caused the western World do follow Roman laws instead biblical? This book where scholars already 300 years go knew it was nonsense under confrontation with reality, science, and historical studies?
